Flutter Riverpod 2.3.6：AutoDisposeNotifier和ref.onDispose自动处理

我正在使用Riverpod版本2.3.6，在ref.onDispose比AutoDisposeNotifier的情况下有一些问题.

1. 我已经在内部版本AutoDisposeNotifier中创建了一个AutoDisposeNotifierProvider和一个ref.onDispose函数. 按下"设置文本文本域"按钮将文本设置为文本和文本域，但当"转到屏幕2"时，ref.onDispose函数不会被触发，除非我在"转到屏幕2"处调用ref.invalidate(newStringLabel).AutoDisposeNotifier不是应该自动触发ref.onDispose功能吗？

2. 我正在使用TextEditingController并试图在ref.onDispose函数中对其进行处置，但收到错误消息"A${notfier.runtimeType}在被处置后被使用.一旦您对${notfier.runtimeType}调用Dispose()，它就不能再使用了."那么我该如何处置TextEditingController美元呢？

import 'package:flutter/material.dart';

void main() {
  runApp(const ProviderScope(
    child: MyApp(),
  ));
}

final textController = TextEditingController();

final newStringLabel =
    AutoDisposeNotifierProvider<NewStringLabel, String>(NewStringLabel.new);

class NewStringLabel extends AutoDisposeNotifier<String> {
  @override
  String build() {
    ref.onDispose(() {
      print('Dispose triggered.');
      //textController.dispose();
      textController.clear();
    });
    return "Init text";
  }

  void toCamelCase() {
    state = 'some text from provider';
    print(state);
  }
}
