deferred_type_flutter for Dart

Pub Version GitHub

Packages for Flutter based on the library deferred_type.

FutureBuilder2

FutureBuilder2, an alternative "FutureBuilder" which is simpler to use than the bundled one provided by default in Flutter.

import "package:deferred_type/deferred_type.dart";

final futureBuilder = FutureBuilder2<String>(
  future: someFuture,
  builder: (context, state) => state.maybeWhen<Widget>(
    inProgress: () => const CircularProgressIndicator(),
    success: (data) => SomeWidget(data),
    error: (error, _stacktrace) => SomeErrorWidget(error),
    // handle fallback cases, must be provided
    // if all states are not handled.
    orElse: () => const FallbackWidget(),
  );
);
