Question

我正在尝试运行我的 flutter 项目，但我收到此错误日志：

/D:/applications/Flutter/flutter/.pub-cache/hosted/pub.dartlang.org/cloud_firestore_platform_interface-5.5.0/lib/src/method_channel/utils/exception.dart:12:7: Error: A non-null value must be returned since the return type 'Never' doesn't allow null.
Never convertPlatformException(Object exception, StackTrace stackTrace) {
      ^

FAILURE: Build failed with an exception.

* Where:
Script 'D:\applications\Flutter\flutter\packages\flutter_tools\gradle\flutter.gradle' line: 1035

* What went wrong:
Execution failed for task ':app:compileFlutterBuildDebug'.
> Process 'command 'D:\applications\Flutter\flutter\bin\flutter.bat'' finished with non-zero exit value 1

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

* Get more help at https://help.gradle.org

BUILD FAILED in 34s
Exception: Gradle task assembleDebug failed with exit code 1

这是 flutter doctor 的输出：

Doctor summary (to see all details, run flutter doctor -v):

注意：我将包名称从默认更改为我需要的名称，如果这可能有助于找到错误！

这可能是由于您将旧版本的 Flutter 与相对较新版本的软件包结合使用造成的。您可以尝试更新 Dart/Flutter 版本，这可能会解决您的问题： https://docs.flutter.dev/development/tools/sdk/upgrading
