firebase - 添加 Firestore 依赖项会导致 Flutter 应用程序出现错误

Question

在我的 flutter 项目中添加 cloud_firestore: ^0.12.10 依赖项会出现错误。

这些是我的项目具有的依赖项:

dependencies:
  url_launcher: ^5.0.0
  flutter_launcher_icons: ^0.7.4

  cloud_firestore: ^0.12.10

  flutter:
    sdk: flutter

  # The following adds the Cupertino Icons font to your application.
  # Use with the CupertinoIcons class for iOS style icons.
  cupertino_icons: ^0.1.2
  firebase_messaging: ^5.1.6

dev_dependencies:
  flutter_test:
    sdk: flutter

flutter_icons:
  android: "launcher_icon"
  ios: true
  image_path: "assets/launcher_icon/LauncherIcon.png"

我尝试使用不同的 cloud_firestore 版本，但都不起作用。

这是终端中 flutter run 命令的输出:

如果您已将 Firebase Core 添加到 gradle 文件，则需要将其更新到 17.2.1，

尽管这是您的项目未启用 androidX 的问题 see how to migrate to androidX

更新

    Cannot fit requested classes in a single dex file (# methods: 81876 > 65536)
com.android.builder.dexing.DexArchiveMergerException: Error while merging dex archives:
The number of method references in a .dex file cannot exceed 64K.
Learn how to resolve this issue at https://developer.android.com/tools/building/multidex.html

您需要启用multidex适合您的应用如下

    android {
    defaultConfig {
        ...
        minSdkVersion 16
        targetSdkVersion 28
        multiDexEnabled true
    }
    ...
}

dependencies {
  implementation "androidx.multidex:multidex:2.0.0"
}
