Minimal code example

Code sample

                    Builder(
                      builder: (context) {
                        final formState = FormBuilder.of(context);
                      },
                    );

Current Behavior

Currently, if you call FormBuilder.of in builder, it calls context.findAncestorStateOfType() which reduces the performance of the application because findAncestorStateOfType enumerates all parent nodes in the tree until it finds FormBuilderState.
In addition, with this approach, the current element is not updated when FormBuilderState changes.

Expected Behavior

FormBuilder.of must use context.dependOnInheritedWidgetOfExactType. Also InheritedWidget must be implemented for FormBuilderState.

  static FormBuilderState? of(BuildContext context, [bool listen = false]) {
    if (listen) {
      return context
          .dependOnInheritedWidgetOfExactType<_FormBuilderScope>()
          ._formState;
    }
    return context.findAncestorStateOfType<FormBuilderState>();
  }

Steps To Reproduce

1. Create any widget.
2. Wrap it in FormBuilder
3. In the widget's build method, call FormBuilder.of(context)
