安裝 cloud_firestore 依賴項后 Android 構建錯誤

Question

我想使用 cloud_firestore 依賴項將我的應用程序連接到 Cloud Firestore，但是在安裝此依賴項后 android 出現了問題。 我收到了這個錯誤錯誤的圖片

之后我無法構建 android 應用程序來在模擬器上測試它，但在 iOS 上它工作得很好。

正如我在之前閱讀的文檔中發現的那樣，我也已經遷移到了 androidx。 所以有人有任何想法來解決這個問題嗎？

您將面臨的前 2 個錯誤和解決方案：

錯誤 1：

解決方案

我遇到了同樣的問題，並結合了兩個建議的修復程序以使其最終起作用：

1：minSdkVersion 21，改為23

2：運行“flutter pub upgrade”=問題已修復！

仔細檢查修復是什么：我還恢復到 21 並無效 + flutter clean 並且問題再次出現。 然后我改為23，警告消失了！

解決方案：

我收到了同樣的錯誤，但是在flutter clean和flutter packages get之后一切正常。
