identityFuture<T> function

Future<T> identityFuture<T>(
  1. T a

Returns the given a, wrapped in Future.value.

Same as idFuture.

Shortcut function to return the input parameter:

final either = Either<String, int>.of(10);

/// Without using `identityFuture`, you must write a function to return
/// the input parameter `(l) async => l`.
final noId = await either.match((l) async => l, (r) async => '$r');

/// Using `identityFuture`, the function just returns its input parameter.
final withIdentityFuture = either.match(identityFuture, (r) async => '$r');


Future<T> identityFuture<T>(T a) => Future.value(a);
