Provider overrides

In Riverpod, all providers can be overridden to change their behavior. This is useful for testing, debugging, or providing different implementations in different environments, or even Scoping providers.

Overriding a provider is done at on ProviderContainers/ProviderScopes, using the overrides parameter. In it, you can specify a list of instructions on how to override a specific provider.

Such "instruction" is created using your provider, combined with value methods named overrideWithSomething.
There are a bunch of these methods available, but all of them have their name starting with overrideWith. This includes:

• overrideWith
• overrideWithValue
• overrideWithBuild

A typical override looks like this:

ProviderScope

void main() {
  runApp(
    ProviderScope(
      overrides: [
        // Your overrides are defined here.
        // The following shows how to override a "counter provider"
        // to use a different initial value.
        counterProvider.overrideWith((ref) => 42),
      ]
    )
  );
}

ProviderContainer

final container = ProviderContainer(
  overrides: [
    // Your overrides are defined here.
    // The following shows how to override a "counter provider"
    // to use a different initial value.
    counterProvider.overrideWith((ref) => 42),
  ]
);
