build method

@override Widget build()

Subclasses should override this function to actually call the appropriate build function (e.g., StatelessWidget.build or State.build) for their widget.

Implementation

@override
Widget build() {
  state.needObservation = true;
  try {
    return super.build();
  } on AccessWhileLoadingError {
    return state.buildIndicator(this);
  } catch (e) {
    rethrow;
  } finally {
    state.needObservation = false;
  }
}
