在尝试向我的应用程序添加集成测试时，我遵循了以下步骤：
- 在项目根目录创建一个文件夹“test_driver”
- 在包含 (1) 的文件夹中创建文件 app.dart
- 以及一个文件“app_test.dart”（2）
(1)
import 'package:flutter/cupertino.dart';
import 'package:flutter/material.dart';
import 'package:flutter_driver/driver_extension.dart';
void main() {
enableFlutterDriverExtension();
runApp(Text(
'Blabla'
));
}
(2)
void main() {
group('Counter App', () {
});
}
我自愿根本没有实施任何测试并使用 Text 小部件，但我得到了这个错误：

我的 pubspec 看起来像这样：

description: A new Flutter application to learn thanks to the SRS System.
# The following defines the version and build number for your application.
# A version number is three numbers separated by dots, like 1.2.43
# followed by an optional build number separated by a +.
# Both the version and the builder number may be overridden in flutter
# build by specifying --build-name and --build-number, respectively.
# In Android, build-name is used as versionName while build-number used as versionCode.
# Read more about Android versioning at https://developer.android.com/studio/publish/versioning
# In iOS, build-name is used as CFBundleShortVersionString while build-number used as CFBundleVersion.
# Read more about iOS versioning at
# https://developer.apple.com/library/archive/documentation/General/Reference/InfoPlistKeyReference/Articles/CoreFoundationKeys.html

我将非常感谢任何形式的帮助：D
解决方案：就像@Darshan 所说，我们只需要切换到包含修复的飞镖版本。以下几行帮助我解决了这个问题：
brew upgrade --force dart -- --devel
brew switch dart 2.7.0-dev.2.1
