Hi, I can't find a solution when decoding a json with accent marks. I have this small json

{ "aString": "carpeta sin título" }

As you can see, the word "título" has an accent mark, really common in Spanish.
When I try to run this code through decode I get the following exception:
FormatException: Control character in string

The decode function is really simple:
return json.decode(jsonString);

Any ideas?

Steps to Reproduce

1. Use jsonDecoder with List

Lots of Dart and Flutter users don't even know about package:convert or dart:convert, or when they do it seems difficult to get started - most code samples I've seen folks write static functions in the form of T convert<S, T>(S input) and ignore these packages.

Could we consider adding some simple short-hand classes/functions to make use easier?

• A MapConverter that uses a backing Map<S, T> to do simple conversions:

class MapConverter<S, T> implements Converter<S, T> {
  const MapCodec(Map<S, T> map) => ...
}

final hexToName = const MapConverter(const {
  0x00: 'Zero',
  0x01: 'One',
  0x02: 'Two',
});

main() {
  print(hexToName.convert(0x01)); // Outputs 'One'.
}

• A top-level asConverter<S, T>(S Func1<T> function)

main() {
  var /*Converter<int, String>*/ hexToName = asConverter((int value) {
    switch (value) {
      case 0x00: return 'Zero';
      ...
    }
  });
}

• A top-level asCodec<S, T>(Converter<S, T> encoder, Converter<T, S> decoder)

main() {
  var /*Codec<int, String>*/ hexCodec = asCodec(hexToName, nameToHex);
}

Hi,

I have an issue with mapped iterables, the conversion fails with the error:

Uncaught Error: Converting object to an encodable object failed: Instance of 'MappedListIterable<int, String>'

Here it is a sample code to reproduce the issue:

import 'dart:convert';

void main() {
  final Iterable<int> items = [1,2];
  final items2 = items.map((i) => i.toString()); 
  print(jsonEncode(items2));
}

for now to make it working I simply have to add a .toList() after the mapping.

The follwing minimum pub spec:

name: test_null

environment:
  sdk: '>=2.12.0-0 <3.0.0'

dependencies:
  convert: ^3.0.0-nullsafety.0

dev_dependencies:
  test: ^1.16.0-nullsafety.12

Causes the version solver to fail with:

The current Dart SDK version is 2.12.0-29.10.beta.

Because shelf_static >=0.1.0+1 <0.2.8 requires SDK version >=1.0.0 <2.0.0 or >=2.0.0-dev.55.0 <2.0.0 and no versions of shelf_static match >0.2.8 <0.3.0, shelf_static >=0.1.0+1 <0.2.8-∞ or >0.2.8 <0.3.0 is forbidden.
And because shelf_static 0.2.8 depends on convert >=1.0.0 <3.0.0, shelf_static >=0.1.0+1 <0.3.0 requires convert >=1.0.0 <3.0.0.
Because no versions of test match >1.16.0-nullsafety.12 <2.0.0 and test 1.16.0-nullsafety.12 depends on shelf_static ^0.2.6, test ^1.16.0-nullsafety.12 requires shelf_static ^0.2.6.
Thus, test ^1.16.0-nullsafety.12 requires convert >=1.0.0 <3.0.0.
So, because test_null depends on both convert ^3.0.0-nullsafety.0 and test ^1.16.0-nullsafety.12, version solving failed.

The data from MongoDB this data contains a value Int64 type.
This data can't convert to json via jsonEncode function.
The error message is:

Converting object to an encodable object failed: Instance of 'Int64'

Is it a bug or not support?

Flutter received a request to officially support GBK encoding (flutter/flutter#45014), and it seemed more appropriate as a Dart request.

It seems that a decent percentage of Chinese websites run on GBK encoding (https://w3techs.com/technologies/segmentation/sl-cnter-/character_encoding). As far as I understand, GBK is an extension of GB2312, which appears on the chart.

According to our user, there are third-party packages like fast_gbk, but our user claims that bugs in those packages with some special characters are prevent their use in a release version of their app.

Would it be a huge effort to officially support GBK encoding in Dart?

Hi folks,
Dart fails to jsonDecode a valid json string which i copied from typicode Posts with \n in it.
please see

• https://gist.github.com/JoeCodeswell/a565c505e8244bf9105048e874a6adc8
• https://dartpad.dev/a565c505e8244bf9105048e874a6adc8

To see non error behaviour comment out lines 29 & 30.

I need to count on being able to decode good json.

Any help for a workaround would be appreciated.
Thanks.
Love and peace,
Joe Dorocak

When decoding a base64 through the website : https://www.base64decode.org
I can see the all info, including fields added by a legal partner (right column in table below).
When I display the same base64 within flutter_full_pdf_viewer, info is hidden.

It seems some information is lost in the decoding process, this is how the base64 is treated :

String normalized = base64.normalize(base64Raw);
Uint8List decodedBytes = base64Decode(normalized);
return await writeFile(decodedBytes);

Pdf is displayed within a FutureBuilder using :
PDFViewerScaffold(path: snapshot.data)

Thank you for this package and for any kind of support

How can I fix this?

I'm integrating with the twitter API which describes that data should be "percent encoded". In C# I found that the method that matched Twitters docs was Uri.EscapeDataString. I'm trying to do the same thing in Dart and discovered that none of them methods on the Uri class behaved correctly, but someone pointed me at this package.

This seems to work great for all the characters I've tried, except numbers:

// Dart:
print(percent.encode("1".codeUnits)); // outputs %31

// C#:
Console.WriteLine(Uri.EscapeDataString("1")); // outputs 1

The C# version seems to match twitter definition of "percent encoding" but I'm struggling to find detailed docs on whether this is a standard and if so, which is correct. I'm raising it here in the hope that either a) it's a bug and can be fixed or b) there's another method I want that behaves as C# does/twitter expects.

What if I need traverse a json looking for specific objects based on <key, value, level of nesting>?
We have the reviver in JsonDecoder, but it does not provide the level of <key, value> and accumulate the resulting object (with useless memory consumption) that I won't need.

FixedDateTimeFormatter is a remedy for broken DateFormat (dart-lang/i18n#211) therefore most often people will switch to it from DateFormat.

While DateFormat uses this approach:

/// The following characters are available in explicit patterns:
///
///     Symbol   Meaning                Presentation       Example
///     ------   -------                ------------       -------
///     G        era designator         (Text)             AD
///     y        year                   (Number)           1996
///     M        month in year          (Text & Number)    July & 07
///     L        standalone month       (Text & Number)    July & 07
///     d        day in month           (Number)           10
///     c        standalone day         (Number)           10
///     h        hour in am/pm (1~12)   (Number)           12
///     H        hour in day (0~23)     (Number)           0
///     m        minute in hour         (Number)           30
///     s        second in minute       (Number)           55
///     S        fractional second      (Number)           978
///     E        day of week            (Text)             Tuesday
///     D        day in year            (Number)           189
///     a        am/pm marker           (Text)             PM
///     k        hour in day (1~24)     (Number)           24
///     K        hour in am/pm (0~11)   (Number)           0
///     Q        quarter                (Text)             Q3

FixedDateTimeFormatter uses the other one.

/// The allowed characters are
/// * `Y`	for “calendar year”
/// * `M`	for “calendar month”
/// * `D`	for “calendar day”
/// * `E`	for “decade”
/// * `C`	for “century”
/// * `h`	for “clock hour”
/// * `m`	for “clock minute”
/// * `s`	for “clock second”
/// * `S`	for “fractional clock second”

I agree, that it's nice to make date-letters upper-case and time-letters lower-case (#66 (comment)), but because of the reason described at the beginning of this issue - I think that even more important is to follow "The least surprise rule" and both character casing should be consistent.

utf8.encode It should returns datatype of List<int> right? But actually it didn't, I noticed that Uint8List was returned instead List<int>.
This issue happens because the input encoded by encoder.convert and this returns Uint8List
I hope to fix it soon

Thank You

Base64Decoder cannot convert a base64 string that is split to blocks of a certain length by newlines, like:

PGEgaHJlZj0iaHR0cHM6Ly9mbHV0dGVyLmRldi8iPgogIDxoMSBhbGlnbj0i
Y2VudGVyIj4KICAgIDxwaWN0dXJlPgogICAgICA8c291cmNlIG1lZGlhPSIo
cHJlZmVycy1jb2xvci1zY2hlbWU6IGRhcmspIiBzcmNzZXQ9Imh0dHBzOi8v

Is this the intended behavior? The base64 command can decode it, but I don't know which behavior is the way it should be.

# This shell command works fine.
$ echo "PGEgaHJlZj0iaHR0cHM6Ly9mbHV0dGVyLmRldi8iPgogIDxoMSBhbGlnbj0i

Background

I found this when trying to get the README of a GitHub repository using the REST API. It returns the README file as a base64 encoded string that is split into blocks of a certain length by newlines. I tried to convert this to a String, but always failed while decoding the baase64 string to Unit8List.

// Dart 3.0.5
// http: ^1.1.0

import 'dart:convert';

import 'package:http/http.dart' as http;

// GitHub API:
// https://docs.github.com/en/rest/repos/contents?apiVersion=2022-11-28#get-a-repository-readme
void main() async {
  const owner = "flutter";
  const repo = "flutter";
  final url = Uri.https(
    "api.github.com",
    "repos/$owner/$repo/readme",
  );
  final response = await http.get(
    url,
    headers: {
      "accept": "application/vnd.github+json",
    },
  );
  final json = jsonDecode(response.body);
  // This ↓ line causes "FormatException: Invalid character"
  final content = base64.decode(json["content"]);
  final readme = String.fromCharCodes(content);
  print(readme);
}

Then it throws:

Unhandled exception:
FormatException: Invalid character (at character 61)
PGEgaHJlZj0iaHR0cHM6Ly9mbHV0dGVyLmRldi8iPgogIDxoMSBhbGlnbj0i
                                                            ^

Removing the all newlines will fix this problem.

final content = base64.decode(json["content"].replaceAll("\n", ""));

You can see the returned json from the API as follows:

  -H "X-GitHub-Api-Version: 2022-11-28" \

Hello,
I'm and android developer and I have recently decided to move to dart/flutter,

I'm currently facing a problem where i cannot encode (Hex or base64) Arabic text
below is my sample code

-------------dart hexEncoder---------------------
HexEncoder hexEncoder = hex.encoder;
String utf8Data = 'شربل';
String hexData = hexEncoder.convert(utf8Data.codeUnits);
-------------dart hexEncoder---------------------

-------------dart runtime error---------------------
Testing started at 1:56 PM ...

package:convert/src/hex/encoder.dart 78:5 _convert
package:convert/src/hex/encoder.dart 22:38 HexEncoder.convert
test/security_encryption_test.dart 19:33 main.

FormatException: Invalid byte 0x634. (at offset 0)

flutter_doctor.log

This option work like int.tryParse() that will return int?.

Where are these?

  JsonDecoder().tryConvert(data);
  JsonEncoder().tryConvert(data);

I can create this by

class Json {
  static String? tryEncode(data) {
    try {
      return jsonEncode(data);
    } catch (e) {
      return null;
    }
  }

  static dynamic tryDecode(data) {
    try {
      return jsonDecode(data);
    } catch (e) {
      return null;
    }
  }
}

void main() {
  String? jsonEncode = Json.tryEncode(dataEncoded);
  dynamic jsonDecode = Json.tryDecode(dataDecoded);
  print("jsonEncode: $jsonEncode");
  print("jsonDecode: $jsonDecode");
}

However, I'm uncomfortable with this.
Is it impossible to add this function?

add support to Windows-1252

output of print(json.encode(null) is String); is true. It should return null not "null"

if (password.length > 64) {
final passwordDigest = md5.convert(password);
password = Uint8List.fromList(passwordDigest.bytes);
}

../../../.pub-cache/hosted/pub.dev/enough_mail-2.1.4/lib/src/private/smtp/commands/smtp_auth_cram_md5_command.dart:50:33: Error: A value of type 'List' can't be assigned to a variable of type 'Uint8List'.

• 'List' is from 'dart:core'.
• 'Uint8List' is from 'dart:typed_data'.
  password = passwordDigest.bytes;

please add cp-850 and Windows1252 support

for decoding text in excel MS DOS CSV sheets

void main(List<String> args) async {
  final input = new File( 'C:/MyDartProjects/notifis/notifis_backend/db/planilhas/CIP 2012.csv').openRead();
  
  final codec = const Windows1252Codec(allowInvalid: false);
  final stream = await input.transform(codec).transform(LineSplitter());
  await for (var lineString in stream) {
    var rowsAsListOfValues =
        CsvToListConverter(fieldDelimiter: ';').convert(lineString);
    var lineCsv = rowsAsListOfValues.first;
    print(lineCsv.map((e) => '$e').join(' | '));
  }

  exit(0);
}

The only way we had to decode UTF-16 previously was package:utf which has been discontinued. We should add a utf16 encoder and decoder here.

the json string like this :
[ { "A": "bbbb", "B": "11817" }, { "A": "bbbb", "B": "11817" } ]

when decode by convert,
` else if (json.startsWith("[")) {
//is jsonArray

  List decode = const JsonCodec().decode(json);

..............`
the error found:

flutter: FormatException: Unexpected character (at character 3)
[{A: bbbb, B: 11817}, {A: bbbb, B: 11817}]
^
json: [{A: bbbb, B: 11817}, {A: bbbb, B: 11817}]`

I'm fetching the data from a csv file. The data consists of both ascii & utf-8 item in it. I'm trying to convert the particular data to List with the help of CsvToListConverter but before that I'm getting an error while transforming the code to a list when using

final input = new File(entities[i].path).openRead(); //How I'm reading the file
final fields = await input.transform(utf8.decoder).toList(); //How I'm trying to decode the data

This is how the data is

Hello, I have a problem with percent.encode().
I have an API that is used by the Arabs and can contain Arabic characters. One of the Arabic characters is "خ" and if I want to convert it with this method percent.encode('خ'.codeUnits). The code unit number is 1582 which represents 0x62e in hexadecimal. In this case, I will get an exception because it's out of range of the bytes that this library can convert. and I have this exception Unhandled Exception: FormatException: Invalid byte 0x62. Can you please help me with my problem? are there any alternatives I can use?

hex.decode("1")-> fail
hex.decode("01")-> ok

since toRadixString(16) converts 1 into "1" it makes a problem converting again to List with hex.decode

Solution:
-Count the String.length, if it's odd, do padLeft(srtLength+1,'0')

If this is implemented by default it will prevent bug from happening.

The script would:

• Consume mappings (e.g. https://unicode.org/Public/MAPPINGS/ISO8859/8859-2.TXT)
• Generate Dart source that constructs a CodePage representing that mapping

This would allow developers to generate CodePages for encodings not supported by package:convert.

Hey, so I'm getting fortnite usernames through an api. For example, instead of giving me COCA lightツ., it gives COCA lightã��.

If I hard code any of these special chars (flutter web), it works. And the raw response from the api gives me the good name.
Here's my method:

static dynamic getNameFromId(String id) async {
    final response = await http.get('https://fortniteapi.io/stats?account=$id', headers: {
      'Authorization': FortniteAPI.auth,
    });
    if (response.statusCode == 200) {
      return jsonDecode(response.body)['name'];
    } else {
      return null;
    }
  }

I have the following string that I get from an old API const src = '\u00d8\u00ad' this string is displayed as Ø­, but it should be transformed to '\u062d' to be displayed as ح.

I did some research and found the following pages:
https://www.fileformat.info/info/unicode/char/062d/charset_support.htm
https://unicode.scarfboy.com/?s=%5Cu062d

but I have no idea how to fix this using dart.

https://github.com/dart-lang/utf
https://github.com/dart-lang/html/blob/master/lib/src/char_encodings.dart

I'd argue these all should be in pkg/convert. Perhaps we should deprecate pkg/utf
