添加 Firestore 依赖导致 Flutter 应用程序出错

Question

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

这些是我的项目的依赖项：

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，但其中 none 有效。

这是终端中 flutter run 命令的输出：

Launching lib\main.dart on SM A505F in debug mode...

Answer 1

将这行代码添加到您的 android/build.gradle 文件底部。我认为您错过了添加服务插件的步骤。试试这个

并将cloud_firestore: ^0.12.10 dependency放在firebase_messaging dependency下方。

代码：

apply plugin: 'com.google.gms.google-services'

来自您的日志错误

如果您已将 firebase 核心添加到 gradle 文件中，则需要将其更新至 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

您需要为您的应用程序启用 multidex 如下

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

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

Answer 3

在你的目标中添加这一行 'Runner' 在你的 Podfile 中做块，例如：

# ...
target 'Runner' do
  pod 'FirebaseFirestore', :git => 'https://github.com/invertase/firestore-ios-sdk-frameworks.git', :tag => '8.9.0'
# ...
end
