DisposableBuildContext<T extends State<StatefulWidget>> constructor

DisposableBuildContext<T extends State<StatefulWidget>>(
  1. T _state
)

Creates an object that provides access to a BuildContext without leaking a State.

Creators must call dispose when the State is disposed.

State.mounted must be true.

Implementation

DisposableBuildContext(T this._state)
  : assert(
      _state.mounted,
      'A DisposableBuildContext was given a BuildContext for an Element that is not mounted.',
    ) {
  assert(debugMaybeDispatchCreated('widgets', 'DisposableBuildContext', this));
}
