1. lib/main.dart:1:8: Error: Error when reading '../../../../development/flutter/packages/flutter/lib/material.dart': No such file or directory
出现问题原因: 我更改了flutter的环境变量位置,由原来的~/development/flutter换到~/opt/flutter再次打开flutter项目运行, 报错
解决方案:
- 快捷键
shift+cmd+f搜索Users/xxx/development/flutter替换成Users/xxx/opt/flutter - 找到项目文件下
.dart_tool/package_config.json打开, 然后搜索Users/xxx/development/flutter替换成Users/xxx/opt/flutter
2. The getter 'addressOf' isn't defined for the class 'GUID'.
解决方案: 终端执行下面语句就可以了
$ flutter clean
$ flutter pub get
$ flutter pub upgrade

Error running pod install
Error launching application on iPhone 13.
解决方案: https://github.com/flutter/flutter/issues/104118
进入到下面路径打开podhelper.rb文件, 修改 63 行
/Users/malgee/opt/flutter/packages/flutter_tools/bin/podhelper.rb
continue if xcframework_file.start_with?(".") # Hidden file, possibly on external disk.
改成
next if xcframework_file.start_with?(".")
4. Error (Xcode): ../../../.pub-cache/hosted/pub.flutter-io.cn/file-6.1.2/lib/src/interface/file.dart:15:16: Error: The method 'File.create' has fewer named arguments than those of overridden method 'File.create'.
file版本比较低, 需要升级, 执行完之后升级到了 6.1.4,
解决方案:
pub upgrade
pub get
5. This app is using a deprecated version of the Android embedding.
This app is using a deprecated version of the Android embedding.
To avoid unexpected runtime failures, or future build failures, try to migrate this app to the V2 embedding.
Take a look at the docs for migrating an app: https://github.com/flutter/flutter/wiki/Upgrading-pre-1.12-Android-projects
解决: 修改路径下的文件内容 android->app->src->main->AndroidManifest.xml
- 删除这一行
android:name="io.flutter.app.FlutterApplication"
- 在
平级位置添加

6. error: This requires the 'non-nullable' language feature to be enabled.
pubspec.yaml文件修改
从 Flutter 2（和 Dart 2.12）开始，空安全是新的默认值。这意味着通过指定以下 SDK 约束：
environment:
sdk: '>=2.12.0 <3.0.0'

7.
报错信息
Error (Xcode): Invalid depfile: /Users/xxx/Desktop/Flutter/FlutterProject/github_myDemo/douya/.dart_tool/flutter_build/57ec51b5fb657ca2c2bd8e2da11a3b8a/kernel_snapshot.d
Could not build the application for the simulator.
Error launching application on iPhone 13.
解决方案:
flutter clean
flutter run
8 Android Studio 控制台(Logcat)不输出打印
使用终端运行,可以看到打印输出, 之后换成在用 Android Studio 直接运行就可以打印输出了
flutter run --profile
9 运行卡住 Running Gradle task 'assembleDebug'...
- 打开您的
flutter项目目录。 - 将目录更改为您的
flutter项目目录cd android中的android目录 - 执行
./gradlew clean, 清理 gradle - 再重新构建gradle 执行
./gradlew build或者你可以将这两个命令合并使用./gradlew clean build - 现在运行你的
flutter项目 gradle第一次运行assembleDebug需要一些时间。
