Question

我正在研究cloud_firestore的Flutter应用程序。在我将pubspec.yaml中添加“ cloud_firestore：^ 0.9.0”之前，我的应用程序运行正常

dependencies:
  flutter:
    sdk: flutter
  cloud_firestore:

我试图将cloud_firestore的版本更改为0.8.2甚至根本不包含版本。但我仍然无法正常工作。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"
    }

这是错误消息。

更新：因此我将cloud_firestore版本更改为0.3.0，并且可以正常工作。

我认为这可能与SDK版本有关。我不确定。我不是专家。

environment:
  sdk: ">=2.1.0 <3.0.0"

dependencies:
  cloud_firestore: ^0.3.0
  flutter:
    sdk: flutter

如何解决flutter cloud_firestore依赖性？
