當用戶單擊按鈕時，我想要振動，我實作了HapticFeedback但它不起作用

下面是我的按鈕代碼，我想在用戶按下按鈕時振動它。我還在 AndroidManifest 中添加了權限并嘗試了 HapticFeedback 的所有方法，但沒有一個有效

     Material(
                                      color: Colors.transparent,
                                      child: IconButton(
                                        onPressed: () {
                                          HapticFeedback.vibrate();
                                          CollectionReference ref= FirebaseFirestore.instance
                                              .collection("users")
                                              .doc(FirebaseAuth.instance.currentUser!.uid)
                                              .collection('Favourites');
                                          var data={
                                            'Quote': Show_It[index].quote,
                                            'author': Show_It[index].author,
                                          };
                                          ref.add(data).then((value) => {
                                            Fluttertoast.showToast(msg: "Added to Favourites")
                                          });
                                        },
                                        splashRadius: 20,
                                        splashColor: Colors.redAccent,
                                        icon: Icon(
                                          Icons.favorite,
                                          color: Colors.red,
                                        ),
                                      ),
                                    ),

下面是我的 AndroidManifest 檔案，我在其中應用了振動權限，但仍然沒有任何反應

    <uses-permission android:name="android.permission.VIBRATE" />

            <meta-data

        </activity>
        <!-- Don't delete the meta-data below.

        <meta-data

            android:value="2" />
    </application>
</manifest>

您必須從移動設定啟用振動。
