Trigger the error by clicking/tapping on the TextField

Expected results

No errors.

Actual results

More details in log below:

NoSuchMethodError: tried to call a non-function, such as null:
'core.NoSuchMethodError.withInvocation'

When the exception was thrown, this was the stack:
packages/floating_overlay/main.dart 77:46                           [_isSelectionWithinTextBounds]

Code sample

import 'package:flutter/material.dart';

void main() => runApp(
      MaterialApp(
        home: Scaffold(
          appBar: AppBar(
            title: const Text('Example'),
          ),
          body: TextField(
            controller: DelegatingTextEditingController(),
          ),
        ),
      ),
    );

class DelegatingTextEditingController implements TextEditingController {
  DelegatingTextEditingController([
    TextEditingController? controller,
  ]) : _text = controller ?? TextEditingController();

  final TextEditingController _text;

  @override
  void dispose() {
    _text.dispose();
  }

  @override
  void addListener(VoidCallback listener) {
    _text.addListener(listener);
  }

  @override
  void notifyListeners() {
    _text.notifyListeners();
  }

  @override
  void removeListener(VoidCallback listener) {
    _text.removeListener(listener);
  }

  @override
  TextSpan buildTextSpan({
    required bool withComposing,
    required BuildContext context,
    TextStyle? style,
  }) =>
      _text.buildTextSpan(
        context: context,
        style: style,
        withComposing: withComposing,
      );

  @override
  void clear() => _text.clear();

  @override
  void clearComposing() => _text.clearComposing();

  @override
  TextSelection get selection => _text.selection;
  @override
  set selection(TextSelection newSelection) => _text.selection = newSelection;

  @override
  String get text => _text.text;
  @override
  set text(String newText) => _text.text = newText;

  @override
  TextEditingValue get value => _text.value;
  @override
  set value(TextEditingValue newValue) => _text.value = newValue;

  @override
  bool get hasListeners => _text.hasListeners;
}

More context:

I've filed #148033 before and this has the same end objective. I'm wrapping both classes to create a single controller to a custom TextField within my project.

Later today I'll try to recreate a minimal reproducible code for something that happened on my app. I have two of these DelegatingTextEditingControllers and two TextFields on the same page, I could simply not change my focus to the second TextField while using that DelegatingTextEditingController instance.

Found #148471 which is what I meant. I think I'll close this and defer to that.

Related to #148471

Labeling for further investigation.
