$Future.wrap(Future<T> $value)

Properties

$reified → Future

Fully reify the underlying value so it can be used in a Dart context. For example, recursively transform collections into their underlying $values.

no setter, override

$value → Future<T>

The backing Dart value of this $Value

final

hashCode → int

The hash code for this object.

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

toJS → JSPromise<T>

Available on Future<T>, provided by the FutureOfJSAnyToJSPromise extension

A JSPromise that either resolves with the result of the completed Future or rejects with an object that contains its error.

no setter

toJS → JSPromise<JSAny?>

Available on Future<void>, provided by the FutureOfVoidToJSPromise extension

A JSPromise that either resolves once this Future completes or rejects with an object that contains its error.

no setter
