tizen_interop's Introduction

tizen_interop

pub package

Provides Dart bindings for Tizen native APIs, powered by ffigen.

Usage

To use this package, add ffi and tizen_interop as dependencies in your pubspec.yaml file.

dependencies:
  ffi: ^2.0.1
  tizen_interop: ^0.3.0

Then, import package:ffi/ffi.dart and package:tizen_interop/[TIZEN_VERSION]/tizen.dart in your Dart code.

import 'package:ffi/ffi.dart';
import 'package:tizen_interop/5.5/tizen.dart';

Examples

// Getting a string value from the Native API.
// Prefer using `arena` to allocate memory because it frees the memory
// automatically when the `using` block ends.
String appName = using((Arena arena) {
  Pointer<Pointer<Char>> ppStr = arena();
  if (tizen.app_get_name(ppStr) == 0) {
    // The memory allocated by the Native API must be freed by the caller.
    arena.using(ppStr.value, calloc.free);
    return ppStr.value.toDartString();
  }
  return 'unknown';
});

// Passing a string value to the Native API.
// The memory allocated by the `toNativeChar` method must be freed by
// the caller. The `arena` allocator will free it automatically.
using((Arena arena) {
  Pointer<Char> pKey =
      'tizen_interop_test_key_for_int'.toNativeChar(allocator: arena);
  tizen.preference_set_int(pKey, 100);
});

// Getting an integer value from the Native API.
int preferenceValue = using((Arena arena) {
  Pointer<Char> pKey =
      'tizen_interop_test_key_for_int'.toNativeChar(allocator: arena);
  Pointer<Int> pValue = arena();
  if (tizen.preference_get_int(pKey, pValue) == 0) {
    return pValue.value;
  }
  return 0;
});

// Getting a struct value from the Native API.
int freeMemory = using((Arena arena) {
  Pointer<runtime_memory_info_s> pMemInfo = arena();
  if (tizen.runtime_info_get_system_memory_info(pMemInfo) == 0) {
    return pMemInfo.ref.free;
  }
  return 0;
});

// Both sync and async callbacks are supported as long as they are called on
// the same thread.
tizen.storage_foreach_device_supported(
    Pointer.fromFunction(_storageDevice, false), nullptr);

// Callbacks that are called outside the current thread will cause the error:
// "Cannot invoke native callback outside an isolate".
// See the tizen_interop_callbacks package for a solution.

tizen_interop's Issues

[ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: Invalid argument(s): Failed to lookup symbol 'TizenInteropCallbacksRegisterSendPort': undefined symbol: TizenInteropCallbacksRegisterSendPort

I am using the

How to interact with a TV

I have read the readme and looked at the example but I am not sure how to control a Samsung smart TV running TizenOS

Missing parcel apis

Parcel API has been supported since Tizen 6.5.
However, it is not supported in tizen_interop even in version 7.0.
Would it be possible to add the parcel.h APIs? They are included in the platform/core/base/bundle repository.

Can't use async callback

Due to the thread problem, asynchronous callbacks are currently unavailable.

example of a problem situation

  Pointer<NativeFunction<device_changed_cb>> _batteryChangedCallback =
      Pointer.fromFunction<device_changed_cb>(_batteryChanged);

   int ret = tizen.device_add_callback(
        device_callback_e.DEVICE_CALLBACK_BATTERY_CHARGING,
        _batteryChangedCallback,
        Pointer.fromAddress(0));
    if (ret != device_error_e.DEVICE_ERROR_NONE) {
      throw Exception('Failed to register battery callback');
    }
  }

  static void _batteryChanged(
      int type, Pointer<Void> value, Pointer<Void> userData) {
    print('batteryChanged');
  }

If the charging status is changed, following error will be raised.
error: Cannot invoke native callback outside an isolate.

sample code

https://github.com/WonyoungChoi/tizen_interop_async_test

repro with sample code

  1. git clone https://github.com/WonyoungChoi/tizen_interop_async_test
  2. cd tizen_interop_async_test/example
  3. flutter_tizen run (on emulator)
  4. open "Control Panel" of the emulator and choose "Batter".
  5. Change "Charger" state to "on "or "off".
  6. Application will be terminated with following error:

reason

The above code is executed on the Flutter UI thread, but most of the tizen native callbacks come from the main-loop of the main thread. Dart does not support calls between isolates.

Maybe this package has too many lines to be analyzed by pub.dev.

  • No dartdoc is generated.
  • Cannot pass static analysis. This affects the pub score.
  • The package cannot be marked "Dart 3 ready".

I opened an issue here: dart-lang/pana#1205

Upgrade Dart version

one of external package is required Dart 2.17.1 but current flutter-tizen dart version is Dart version 2.17.0,

Because flextizen depends on youtube_data_api >=1.0.0+1 which requires SDK version >=2.17.1 <3.0.0, version solving failed.

please let me know how to upgrade Dart SDK..
