我是Flutter开发人员，过去两天我一直在努力让我的应用程序适用于Android。这是一个相当大的应用程序，具有许多不同的功能（主要是谷歌地图和 firebase），可以在 iOS 上完美运行。但是，现在我正在尝试让 Android 部分正常工作，由于某些Firebase问题，我似乎根本无法启动该应用程序。

FlutterFire负责大多数 Firebase 包，他们刚刚发布了一些更新。我花了相当多的时间重构我的项目以符合大多数重大更改。我面临的问题与新更新有关。不幸的是，我遇到的错误并没有让我更接近解决方案。我认为这与无法找到google-services.json的 Android 部分有关。正如我所提到的，在 iOS 上一切正常。所以我的逻辑结论是 Flutter 代码也很好。Google/StackOverflow/FlutterFire 问题似乎都将我误导到对我没有答案的问题。

TL;DR编译到 Android 时，Flutter App 无法启动，因为 Firebase 找不到我的 google-services.json。这是堆栈跟踪：

E/flutter (15568): [ERROR:flutter/lib/ui/ui_dart_state.cc(166)] Unhandled Exception: [core/not-initialized] Firebase has not been correctly initialized. Have you added the "google-services.json" file to the project?

如何在另一个扑动应用程序中使用本地颤振包？

我使用以下命令创建了一个包:

flutter create --template=package my_new_package

然后在我的应用程序源代码=> main.dart

import "package:my_new_package/my_new_package.dart" // can not find the package

我想使用 flutter_launcher_icons 更改 flutter 中的应用程序图标：^0.9.2
它在我运行命令时显示错误 错误flutter pub run flutter_launcher_icons:main
的图像

我尝试了很多次但没有新的结果

当我在我的颤振项目中添加 http 依赖项时，我遇到了这个问题。任何人都可以帮我吗？

错误：“ModalBottomSheetRoute”是从“package:flutter/src/material/bottom_sheet.dart”和“package:modal_bottom_sheet/src/bottom_sheet_route.dart”导入的。

导入'material.dart'隐藏ModalBottomSheetRoute；

我正在使用 macOS 并且正在安装 flutter。当我跑到“flutter doctor”时，我遇到了类似的错误

    Doctor summary (to see all details, run flutter doctor -v):\n[\xe2\x9c\x93] Flutter (Channel stable, 3.13.5, on macOS 13.6 22G120 darwin-arm64, locale\n    tr-TR)\n[\xe2\x9c\x93] Android toolchain - develop for Android devices (Android SDK version 34.0.0)\n[!] Xcode - develop for iOS and macOS (Xcode 15.0)\n    \xe2\x9c\x97 Unable to get list of installed Simulator runtimes.\n[\xe2\x9c\x93] Chrome - develop for the web\n[\xe2\x9c\x93] Android Studio (version 2022.3)\n[\xe2\x9c\x93] Connected device (2 available)\n[\xe2\x9c\x93] Network resources\n

我不知道为什么。这个错误的根源是什么？

我正在开发一个颤振应用程序，项目运行完美，但突然项目没有运行，它给了我一个错误。

这是我尝试运行应用程序时收到的错误代码

谁能告诉我为什么会出现此错误？

The current Dart SDK version is 2.12.0.\n\nBecause app requires SDK version >=2.15.1 <3.0.0, version solving failed.\npub get failed (1; Because app requires SDK version >=2.15.1 <3.0.0, version solving failed.)\n

这是我的 flutter --version

我已经导入了一个 Eosdart 包，它有 action.dart 文件，甚至 flutter 也有 action.dart 文件，所以应该选择哪个有冲突。请帮助消除冲突 我在代码中提到了错误详细信息作为注释，其中我收到了错误
