Question

当我将firebase_messaging导入我的应用程序时（在pubspec.yaml和一个import语句中）。我的应用无法构建。在尝试导入firebase_messaging之前，它运行良好。我检查了flutter目录，以确保它是正确的版本以及所有内容。我有点不知所措。

我尝试更新android，然后抖动。

Pubspec.yaml

     dependencies:
  firebase_core: ^0.4.0+6
  firebase_analytics: ^3.0.2
  cloud_firestore: ^0.12.5+1

  firebase_auth: ^0.11.1+6
  google_sign_in: ^4.0.2
  rxdart: ^0.22.0
  css_colors: ^1.0.2
  flutter_auth_buttons: ^0.5.0
  firebase_messaging: ^5.1.2

这是错误消息

好吧，在进行了更多研究之后，我找到了答案。我加了实施'com.google.firebase：firebase-messaging：19.0.1' 到我的应用程序级别gradle文件中，我收到一些警告，但是该应用程序本身可以构建并运行。

导入Firebase_Messaging会使构建失败
