Flutter: Activity recognition/Motion and fitness permission popup not shown in iOS platform

Question

In Flutter, I am not able to ask the user for motion and fitness permission in iOS platform. I am using this library for permission handling and I am using following code

Permission.activityRecognition.request()

// Android
// Asks for permission

// iOS
// No prompt

Solution

The workaround I found was to use Permission.sensors instead of Permission.activityRecognition for iOS platform. The code goes like this:-

Permission getMotionPermission() {
    if(Platform.isAndroid /** Also check if SDK >= 29 **/){
         return Permission.activityRecognition;   
    } else if(Platform.isIOS) {
         return Permission.sensors;
    }
}

// ask for permission
Permission motionPermission = getMotionPermission();
motionPermission?.request();
