when I try to run the moor_shared on Windows I get the following error:

Does anyone know why this happens?

Thanks in advance

This is the output of flutter run -d windows -v

Could not build the precompiled application for the device.

Does anyone has idea about this error? Thank you

It worked good before I upgrade moor and moor_ffi to the latest version.
I think this is caused by the different APIs among these version. Can you update this project to support the latest version of moor and moor_ffi, since I'd like to upgrade these packages to up-to-date ones. Thanks.

unfortunately its not working on windows

When using on my physical Android device, it crashed as follows:

The device is using Android 7.1.2:

But, it work fine on the Android emulator running on the MacOS:

My question is whether moor requires the minimum version of Android to make it works? If yes, I hope to make it support as extent as possible when it comes to Android version, because our product will meet users with different background.

Will Moor save the stack trace in a file on the device? If yes, please tell me where, so that I can send you it.

Am I missing anything before I release the code to a physical device? Thanks.

I'm getting an assert test failure on run widget_test.dart:

The following TestFailure object was thrown running a test:
Expected: exactly one matching node in the widget tree
Actual: _TextFinder:<zero widgets with text "0" (ignoring offstage widgets)>
Which: means none were found but one was expected

The same question was made on stackoverflow too:

TableUtils.insertRow returns a Future<void> however, Database.createCategory tries to cast it to Future<int>. This is causing a crash when trying to add a category.

Added a category and got this exception

**Future<int>** createCategory(String description) {
    return insertRow(
      cs,
      categories,
      CategoriesCompanion(description: Value(description)),
    ) as Future<int>;
  }

db_utils.dart:

databaseUtils.
 **Future<void>** insertRow(
    ChangeStack cs,
    Table table,
    Insertable val,
  ) async {
    final _change = Change(
      val,
      () async => await this.into(table as TableInfo).insert(val),
      (dynamic val) async => await this.delete(table as TableInfo).delete(val),
    );
    cs.add(_change);
  }

Looks like this happens more than once from a cursory glance at the code. I am not at all familiar with this code, this is the second thing I tried when I compiled and ran, and I'm a newbie with Flutter/Dart, so I'm not up to fixing it and doing a pull request. If I decide to use this in a project I'll try to figure it out.

It looks like this code is sparsely maintained so I wasn't going to submit this, but you did merge the pull request recently to handle null support.

How to return SharedDatabase instance for web from constructDb()

I followed moor_shared example and everything was working perfect until I updated moor to v4.

in web.dart file I was constructing SharedDatabase like this before:

web.dart

SharedDatabase constructDb({bool logStatements = false}) {
  return SharedDatabase(WebDatabase.withStorage(
      MoorWebStorage.indexedDbIfSupported('my_database'),
      logStatements: logStatements));
}

but after updating moor to v4 MoorWebStorage is now Future

WebDatabase.withStorage(await MoorWebStorage.indexedDbIfSupported(name))

how can I return the SharedDatabase without Future so that I can use constructDb() because for mobile constructsDb() returns simply SharedDatabase like this:

mobile.dart

SharedDatabase constructDb({bool logStatements = false}) {
  if (Platform.isIOS || Platform.isAndroid) {
    final executor = LazyDatabase(() async {
      final dataDir = await paths.getApplicationDocumentsDirectory();
      final dbFile =
          File(p.join(dataDir.path, 'my_database.sqlite'));
      return VmDatabase(dbFile, logStatements: logStatements);
    });
    return SharedDatabase(executor);
  }
  if (Platform.isMacOS || Platform.isLinux) {
    final file = File('my_database.sqlite');
    return SharedDatabase(
        VmDatabase(file, logStatements: logStatements));
  }
  if (Platform.isWindows) {
    final file = File('my_database.sqlite');
    return SharedDatabase(
        VmDatabase(file, logStatements: logStatements));
  }

  return SharedDatabase(
      VmDatabase.memory(logStatements: logStatements));
} 

Web window screenshot shown in the Readme seems incorrect, because that shows a counter application unlike others showing a todo app
