android - 如何修复 flutter cloud_firestore 依赖项？

Question

我正在开发用于测试 cloud_firestore 的 flutter 应用程序。在我将“cloud_firestore: ^0.9.0”添加到我的 pubspec.yaml 之前，我的应用程序运行良好

dependencies:
  flutter:
    sdk: flutter
  cloud_firestore: 

我曾尝试将 cloud_firestore 的版本更改为 0.8.2，甚至根本不包含版本。但我仍然无法让它工作。我还尝试将“android\app\build.gradle”中的 minSdkVersion 从 16 更改为 21。

  defaultConfig {
        // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
        applicationId "com.example.baby_names"
        minSdkVersion 21
        targetSdkVersion 28
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }

这是错误信息。

我的应用程序将不再启动。我需要帮助。提前谢谢你。

更新:所以我将 cloud_firestore 版本更改为 0.3.0，它起作用了。

我觉得可能和sdk版本有关。我不知道。我不是专家。

environment:
  sdk: ">=2.1.0 <3.0.0"

dependencies:
  cloud_firestore: ^0.3.0
  flutter:
    sdk: flutter
