How can I mock on riverpod3.0.0?

[normidar]

I am using riverpod3.0.0-dev My class like this:

@Riverpod(keepAlive: true)
class TextLanguage extends _$TextLanguage {
  @override
  TextRecognitionScript build() {
    return TextRecognitionScript.latin;
  }

  void setScript(TextRecognitionScript script) {
    state = script;
  }
}

And I will test my widget like:

testWidgets('Counter increments smoke test', (WidgetTester tester) async {
  // Build our app and trigger a frame.
  await tester.pumpWidget(
     ProviderScope(
      overrides: [
        textRecognitionProvider.overrideWith((ref) => TextRecognitionScript.japanese),
      ],
      child: Main(),
    ),
  );
});

I got error:

The argument type 'TextRecognition Function(dynamic)' can't be assigned to the parameter type 'TextRecognition Function()'. dart[argument_type_not_assignable](https://dart.dev/diagnostics/argument_type_not_assignable)
The return type 'TextRecognitionScript' isn't a 'TextRecognition', as required by the closure's context.dart[return_of_invalid_type_from_closure](https://dart.dev/diagnostics/return_of_invalid_type_from_closure)

How can I fix this?

@rrousselGit
I'm following the documentation to try this, can you help me?

[gdurandrexel]

overrides: [
textRecognitionProvider.overrideWithValue(TextRecognitionScript.japanese),
],

[normidar]

@rrousselGit @gdurandrexel

there are no overrideWithValue function in riverpod3.

[snapsl]

Are you trying to override the correct provider? According to your example, it should be called textLanguageProvider not textRecognitionProvider.

[normidar]

@snapsl @gdurandrexel

It doesn't has overrideWithValue method in textRecognitionProvider.

Do your Editor show the overrideWithValue method on Riverpod3?

[snapsl]

I am not using riverpod 3.0 dev build. But maybe you can look into the generated *.g.dart file for something like

  /// {@macro riverpod.override_with_value}
  Override overrideWithValue(int value) {
    return $ProviderOverride(
      origin: this,
      providerOverride: $ValueProvider<int>(value),
    );
  }

If you are sure that it is not a problem on your side, then you could fill an issue. Also specify the flutter and package versions you are using.

@snapsl
Witch riverpod version do you use?

[normidar]

There are not overrideWithValue function on my *.g.dart file.

I am using 2.5.1 now but I can't fix it.

NotifierProvider cannot use overrideWithValue(). if you want to override the initial value of NotifierProvider, you can do so by writing the following.

@Riverpod(keepAlive: true)
TextRecognitionScript defaultTextRecognitionScript(DefaultTextRecognitionScriptRef ref) {
  return TextRecognitionScript.latin;
}

@Riverpod(keepAlive: true)
class TextLanguage extends _$TextLanguage {
  @override
  TextRecognitionScript build() {
    return ref.watch(defaultTextRecognitionScriptProvider);
  }

  void setScript(TextRecognitionScript script) {
    state = script;
  }
}

testWidgets('Counter increments smoke test', (WidgetTester tester) async {
  await tester.pumpWidget(
     ProviderScope(
      overrides: [
        defaultTextRecognitionScriptProvider.overrideWithValue(TextRecognitionScript.japanese),
      ],
      child: Main(),
    ),
  );
});
