【问题描述】：

下面是我的按钮代码，我想在用户按下按钮时振动它。我还在 AndroidManifest 中添加了权限，并尝试了 HapticFeedback 的所有方法，但它们都不起作用

     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 文件，我在其中应用了振动权限，但仍然没有任何反应

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.make_your_day">
    <uses-permission android:name="android.permission.VIBRATE" />
   <application
        android:label="make_your_day"
        android:name="${applicationName}"
        android:icon="@mipmap/ic_launcher">
        <activity
            android:name=".MainActivity"
            android:exported="true"
            android:launchMode="singleTop"
            android:theme="@style/LaunchTheme"
            android:configChanges="orientation|keyboardHidden|keyboard|screenSize|smallestScreenSize|locale|layoutDirection|fontScale|screenLayout|density|uiMode"
            android:hardwareAccelerated="true"
            android:windowSoftInputMode="adjustResize">
            <!-- Specifies an Android theme to apply to this Activity as soon as

                 to determine the Window background behind the Flutter UI. -->
            <meta-data
              android:name="io.flutter.embedding.android.NormalTheme"
              android:resource="@style/NormalTheme"
              />
            <intent-filter>
                <action android:name="android.intent.action.MAIN"/>
                <category android:name="android.intent.category.LAUNCHER"/>
            </intent-filter>
        </activity>
        <!-- Don't delete the meta-data below.
             This is used by the Flutter tool to generate GeneratedPluginRegistrant.java -->
        <meta-data
            android:name="flutterEmbedding"
            android:value="2" />
    </application>
</manifest>

你是否导入了这个：

import 'package:flutter/services.dart';
