這篇文章主要介紹了Flutter permission_handler 權(quán)限插件的使用,本文給大家介紹的非常詳細(xì)，對大家的學(xué)習(xí)或工作具有一定的參考借鑒價值，需要的朋友可以參考下

編譯環(huán)境：Flutter 版本v1.12.hotfix9 dart SDK：2.7.2

1 pubspec.yaml中引入：

# 權(quán)限
permission_handler: ^3.2.0

ios中info.plist配置（根據(jù)權(quán)限情況使用）：

 <!-- Permission options for the `location` group -->
 <key>NSLocationWhenInUseUsageDescription</key>
 <string>Need location when in use</string>
 <key>NSLocationAlwaysAndWhenInUseUsageDescription</key>
 <string>Always and when in use!</string>
 <key>NSLocationUsageDescription</key>
 <string>Older devices need location.</string>
 <key>NSLocationAlwaysUsageDescription</key>
 <string>Can I haz location always?</string>

 <!-- Permission options for the `mediaLibrary` group -->
 <key>NSAppleMusicUsageDescription</key>
 <string>Music!</string>
 <key>kTCCServiceMediaLibrary</key>
 <string>media</string>

 <!-- Permission options for the `calendar` group -->
 <key>NSCalendarsUsageDescription</key>
 <string>Calendars</string>

 <!-- Permission options for the `camera` group -->
 <key>NSCameraUsageDescription</key>
 <string>camera</string>

 <!-- Permission options for the `contacts` group -->
 <key>NSContactsUsageDescription</key>
 <string>contacts</string>

 <!-- Permission options for the `microphone` group -->
 <key>NSMicrophoneUsageDescription</key>
 <string>microphone</string>

 <!-- Permission options for the `speech` group -->
 <key>NSSpeechRecognitionUsageDescription</key>
 <string>speech</string>

 <!-- Permission options for the `sensors` group -->
 <key>NSMotionUsageDescription</key>
 <string>motion</string>

 <!-- Permission options for the `photos` group -->
 <key>NSPhotoLibraryUsageDescription</key>
 <string>photos</string>

 <!-- Permission options for the `reminder` group -->
 <key>NSRemindersUsageDescription</key>
 <string>reminders</string>

2 代碼中具體使用：

 void chosePhoto(int index) async {
 PermissionHandler().requestPermissions(
 [PermissionGroup.photos, PermissionGroup.camera]).then((map) {
 if (map[PermissionGroup.photos] == PermissionStatus.granted ||
  map[PermissionGroup.camera] == PermissionStatus.granted) {
 chosePhotoFromPhone(context, index);
 }
 });
 }

3 總結(jié)：

在使用的過程中可能會出現(xiàn)androidX 或者Swift語言的適配，這時候需要根據(jù)具體情況進(jìn)行修改。
