google_maps_flutter在发布中不起作用

Question

我一年前创建了一个简单的flutter应用程序(仅限Android(，但忘记了它。现在突然之间，它不得不投入生产。此应用程序包含firebase验证、firestore数据库和带有Places API的谷歌地图。

dependencies:
flutter:
sdk: flutter
flutter_localizations: # Add this line
sdk: flutter
firebase_auth: ^0.14.0+5
provider: ^3.1.0
animated_text_kit: ^3.1.2

flutter_rating_bar: ^3.1.0
cloud_firestore: ^0.12.9+4
google_maps_flutter: ^0.5.30

在调试模式下一切都很好。但现在，当我开始发布并将其放入Play控制台时，我遇到了一个大问题。谷歌地图(_它是应用程序的关键元素(不起作用(不可见(。API工作场所BTW。我已经阅读了这里的所有问题，并在Google开发者控制台和Firebase控制台中玩了API密钥限制(指纹(等等。无效。当我在本地机器上构建新版本时；flutter构建appbundle"；我在日志中看到错误。

当我从Play Store(内部测试(获得应用程序后，在设备上以发布模式运行应用程序时，我在有关谷歌地图的日志中看到了这个错误

我是一名JS开发人员，所以Dart很容易掌握，但Java对我来说很难。请阐明这个问题。这里发生了什么，在这种情况下该怎么办？我将不胜感激。PS…在本地调试模式下一切都很好。此外，我创建了我的应用程序的副本，删除了除了与谷歌地图包相关的所有代码和依赖项，并构建了新版本。没有出现地图。所以问题是这个谷歌地图只有，并没有依赖冲突，我认为！！！还有一个观察-图像选择器和URL启动器在Google Play控制台发布时也不起作用。但如果我运行flutter run——本地释放，一切都会好起来。我想知道-也许我必须在Play控制台中添加一些访问策略或其他什么

Answer 1

经过很长时间的搜索，主要归功于Ruslanbek0809的帮助，我终于解决了这个问题
在android/app/build.gradle中，我向buildTypes 添加了：
shrinkResources false和minimyEnabled false

buildTypes {
release {
signingConfig signingConfigs.release
shrinkResources false
minifyEnabled false
}
}

奇迹发生了

Answer 2

确保在Manifest:中添加了这行代码

<uses-permission android:name="android.permission.INTERNET" />

Answer 3

• 卸载应用程序
• 运行颤振命令flutter clean
• 再次运行您的应用程序

注意：我并没有完全阅读这个问题。这就是为什么这个答案不是为了发布，而是为了调试apk。
