Flutter 构建找不到 'dart:html'

Question

我试过运行 flutter clean .我试过在 beta 之间切换和 stable channel 。
编译器似乎正在尝试添加浏览器支持的内容，但我正在编译 APK。
Flutter Web 支持已禁用。我以前编译这个没有问题。看起来问题的根源可能是 sentry我正在使用的包。

我怎样才能让应用程序再次编译？

这是 build apk 的输出

$ 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

我最终发现了我的错误。
我的错误是明确导入

import 'package:sentry/browser_client.dart';

代替

import 'package:sentry/sentry.dart';
