Flutter Image_Picker 在打开相机时崩溃 iOS 应用程序

Question

everything works perfect in Android when I open gallery or Camera, but when I try on iOS (emulator and real device) gallery works perfect but as soon as I press the Camera option the app crash without console logs only "Lost connection to device"

 // get image File camera
 _getFromCamera(BuildContext context) async {
   XFile? pickedFile = await ImagePicker().pickImage(
     source: ImageSource.camera,
     maxWidth: 1800,
     maxHeight: 1800,
   );
   File rotatedImage =
       await FlutterExifRotation.rotateAndSaveImage(path: pickedFile!.path);
   if (pickedFile != null) {
     image = rotatedImage;
     //File(pickedFile.path);
     final userId = widget.id;
     widget.bloc.uploadProfilePicture(image, userId);
   }
 }

Then I called the function in a Icon button

TextButton.icon(
                     icon: Icon(
                       Icons.photo_camera,
                       color: Theme.of(context).primaryColor,
                     ),
                     label: Text(
                       AppLocalization.of(context)!
                           .getTranslatedValues("cameraLbl")!,
                       style: TextStyle(
                           color: Theme.of(context).colorScheme.secondary,
                           fontWeight: FontWeight.bold),
                     ),
                     onPressed: () {
                       _getFromCamera(context);
                       Navigator.of(context).pop();
                     },
                   )

Answer 1

You have to add additional permissions inside the info.plist file

Add these entries inside it:

<key>NSPhotoLibraryUsageDescription</key>
<string>Needs PhotoLib access</string>

<key>NSCameraUsageDescription</key>
<string>Needs camera access</string>

To add permissions in flutter application, you need to add permissions in both android manifest and info.plist file.

Also you can use any string inside the string tag, and that string would be shown to the user as why the user needs to give permission.

Answer 2

Add the permisson keys inside the info.plist file (located in {app_folder}/ios/Runner/Info.plist

Here is the info.plist file located

and add

<key>NSPhotoLibraryUsageDescription</key>
<string>Needs PhotoLib access</string>

<key>NSCameraUsageDescription</key>
<string>Needs camera access</string>

this will display the permission window for the camera and gallery
