By adding the thunkMiddleware to any of your built_redux stores, any action dispatched that's payload meets the typedef signature dynamic thunk(MiddlewareApi api) will be called.


Create a function that returns a thunk configured with an url, that dispatches an action (onRequestResolved) in async code:

dynamic httpRequestThunk(String url) => (MiddlewareApi<Counter, CounterBuilder, CounterActions> api) {
  // call the web server asynchronously.

Add an thunk dispatcher to your ReduxActions:

abstract class CounterActions extends ReduxActions {
  ActionDispatcher<Thunk<Counter, CounterBuilder, CounterActions>> thunkDispatcher;
  ActionDispatcher<String> onRequestResolved;

  // factory to create on instance of the generated implementation of CounterActions
  factory CounterActions() => new _$CounterActions();

The action with Thunk isn't mapped to a reducer.

Register the Thunk middleware:

var store = new Store<Counter, CounterBuilder, CounterActions>(
  new Counter(),
  new CounterActions(),
  middleware: <Middleware<TestCounter, TestCounterBuilder, TestCounterActions>>[

Dispatch the thunk

  • Maintain CHANGELOG.md.

    Changelog entries help clients to follow the progress in your code.

  • The description is too short.

    Add more detail about the package, what it does and what is its target use case. Try to write at least 60 characters.

  • Package is pre-v1 release.

    While there is nothing inherently wrong with versions of 0.*.*, it usually means that the author is still experimenting with the general direction API.

  • Maintain an example.

    Create a short demo in the example/ directory to show how to use this package. Common file name patterns include: main.dart, example.dart or you could also use built_redux_thunk.dart.
