如何在Flutter中將來自FirebaseAuth的用戶ID鏈接到來自Firestore的用戶ID

當我的用戶注冊時，他會輸入他的電子郵件、用戶名和密碼。電子郵件和密碼存盤在 Firebase Auth 資料庫中。因此，為該用戶創建并關聯了一個 Id。（例如，kmupeDXnfEYnhbdpkvLUoFbIjnb2）。現在我想創建一個用戶個人資料（個人資料圖片、用戶名等）。為此，我必須創建一個 Firestore 集合和檔案，其用戶名和 ID 鏈接到 firebase 身份驗證 (kmupeDXnfEYnhbdpkvLUoFbIjnb2)。我不知道該怎么做有人可以幫助我嗎？非常感謝 ！

回呼FirebaseAuth.instance.createUserWithEmailAndPassword(是型別。UserCredential您可以uid通過以下方式訪問UserCredential：value.user.uid
