如何解决 flutter 中的 'allowsBackgroundLocationUpdates' 错误

Question

当我运行我的 flutter 应用程序时，我收到了一些与位置设置相关的错误。

错误 1：

/Users/mustafazaki/Downloads/flutter/.pub-cache/hosted/pub.dartlang.org/location-3.2.4/ios/Classes/LocationPlugin.m:84:43: note: enclose 'allowsBackgroundLocationUpdates' in an @available check to silence this warning result(self.clLocationManager.allowsBackgroundLocationUpdates ? @1 : @0);

错误2：

错误 3：

/Users/mustafazaki/Downloads/flutter/.pub-cache/hosted/pub.dartlang.org/location-3.2.4/ios/Classes/LocationPlugin.m:92:36: note: enclose 'setShowsBackgroundLocationIndicator:' in an @available check to silence this warning self.clLocationManager.showsBackgroundLocationIndicator = enable;

Answer 1

尝试将此代码添加到您的 info.plist ios->Runner->Info.plist <dict> 标签内。

<key>NSLocationAlwaysAndWhenInUseUsageDescription</key>
<string>Location permission</string>
<key>NSLocationAlwaysUsageDescription</key>
<string>Location permission</string>
<key>NSLocationUsageDescription</key>
<string>Location permission</string>
<key>NSLocationWhenInUseUsageDescription</key>
<string>Location permission</string>

停止您的应用程序，然后在终端中运行 :

颤抖干净
flutter pub get
颤动运行
