编译环境:flutter 版本v1.12.hotfix9 dart sdk:2.7.2

1 pubspec.yaml中引入:

  #  权限
  permission_handler: ^3.2.0

ios中info.plist配置(根据权限情况使用):

 <!-- 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 代码中具体使用:

 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 总结:

在使用的过程中可能会出现androidx 或者swift语言的适配,这时候需要根据具体情况进行修改。
