overrideWithProvider method
Overrides the behavior of this provider with another provider.
Some common use-cases are:
- testing, by replacing a service with a fake implementation, or to reach a very specific state easily.
- multiple environments, by changing the implementation of a class based on the platform or other parameters.
This function should be used in combination with ProviderScope.overrides
or ProviderContainer.overrides
:
final myService = Provider((ref) => MyService());
runApp(
ProviderScope(
overrides: [
myService.overrideWithProvider(
// Replace the implementation of MyService with a fake implementation
Provider((ref) => MyFakeService())
),
],
child: MyApp(),
),
);
Implementation
ProviderOverride overrideWithProvider(
AutoDisposeProviderBase<Object?, Listened> provider,
) {
return ProviderOverride(provider, this);
}
