Flutter发布的应用在启动时崩溃。

Question

当我在调试模式下运行应用程序时，它正常工作，但是在生成签名的包/APK版本后，启动应用程序时应用崩溃了。 我尝试在发布模式下运行flutter，并显示了这个控制台。

你能分享一下你的pubspec.yaml文件或者描述一下你正在使用哪些包吗？ - tomerpacific

似乎是Firebase库的问题：https://stackoverflow.com/questions/63162392/including-implementation-com-google-firebasefirebase-analytics17-4-4-cause/71876935#71876935 - Hardik Mehta

Answer 1

我猜测错误与 Firebase 设置有关。请查看官方文档上的指南。

验证是否正确添加了以下行：

build.gradle

buildscript {

  repositories {
    // Check that you have the following line (if not, add it):
    google()  // Google's Maven repository
  }

  dependencies {
    // ...

    // Add the following line:
    classpath 'com.google.gms:google-services:4.3.10'  // Google Services plugin
  }
}

allprojects {
  // ...

  repositories {
    // Check that you have the following line (if not, add it):
    google()  // Google's Maven repository
    // ...
  }
}

app/build.gradle

apply plugin: 'com.android.application'
// Add the following line:
apply plugin: 'com.google.gms.google-services'  // Google Services plugin

android {
  // ...
}

在这样做之后，运行 flutter clean 和 flutter pub get 命令并重新构建。
