如何在flutter_driver测试中在TextField上生成键盘事件ENTER

import 'package:flutter_driver/flutter_driver.dart';
import 'package:test/test.dart';
import 'dart:io';

void main() {
  group('TextField Keyboard Event Test', () {
    FlutterDriver driver;

    setUpAll(() async {
      // 连接到Flutter应用程序
      driver = await FlutterDriver.connect();
    });

    tearDownAll(() async {
      // 关闭连接
      if (driver != null) {
        driver.close();
      }
    });

    test('Generate Keyboard Event on TextField', () async {
      // 找到TextField的控件
      final textFieldFinder = find.byValueKey('your_textfield_key');

      // 在TextField上生成键盘事件ENTER
      await driver.tap(textFieldFinder);
      await driver.enterText('Your text');
      await driver.waitFor(find.text('Your text'));
      await driver.tap(find.text('ENTER'));

      // 验证是否成功生成键盘事件ENTER
      expect(await driver.getText(textFieldFinder), 'Your text\n');
    });
  });
}
