问题描述
我已经尝试运行 flutter clean 。我尝试在 beta 和 stable 频道之间进行切换。
编译器似乎正在尝试添加一些内容以支持浏览器，但我正在编译APK。
Flutter Web支持已禁用。以前我编译它没有问题。看来问题的根源可能是我使用的 sentry 软件包。
I've tried running flutter clean. I've tried changing between the beta and stable channel.
The compiler seems to be trying to add things for browser support but I am compiling an APK.
Flutter Web support is disabled. I had no trouble compiling this before. It looks like the source of the problem might be the sentry package which I am using.
如何获取
这是 build apk
$ flutter build apk
You are building a fat APK that includes binaries for android-arm, android-arm64, android-x64.
If you are deploying the app to the Play Store, it's recommended to use app bundles or split the APK to reduce the APK size.
To generate an app bundle, run:
flutter build appbundle --target-platform android-arm,android-arm64,android-x64
Learn more on: https://developer.android.com/guide/app-bundle
To split the APKs per ABI, run:
flutter build apk --target-platform android-arm,android-arm64,android-x64 --split-per-abi
Learn more on: https://developer.android.com/studio/build/configure-apk-splits#configure-abi-split

推荐答案
我最终发现了自己的错误。
我的错误是明确导入
I found my mistake eventually. My mistake was explicitly importing
import 'package:sentry/browser_client.dart';
而不是
import 'package:sentry/sentry.dart';
