Flutter Firebase firestore.data[“”] 錯誤

Question

我正在使用 firebase " cloud_firestore: ^0.14.3+1 " 和我的 flutter 應用程序和 ım 托盤從 firebase 獲取數據。

 Widget searchList(){
  return ListView.builder(
    itemCount: searchSnapshot.docs.length,
    itemBuilder: (context, index){
      return SearchTile(
        userName: searchSnapshot.docs[index].data["name"],
        userEmail: searchSnapshot.docs[index].data["email"],
      );
    });
 }

Answer 1

像這樣做。 你需要調用 data()['fieldName']

  return SearchTile(
    userName: searchSnapshot.docs[index].data()["name"],
    userEmail: searchSnapshot.docs[index].data()["email"],
  );
