Answer 1

确保您使用的是最新cloud_firestore版本。然后执行：

flutter clean
flutter packages get

更新，从cloud_firestore0.14.0 版开始：

setData()被替换为set()。其他有用的链接：

未为“Firestore”类型定义 getter“实例”

Answer 2

就我而言，我执行了以下步骤：

flutter clean
flutter packages get

卸载应用

更新：/android/app/build.gradle

defaultConfig {
    ...
    multiDexEnabled true
}

再次运行。

希望这可以帮助
