I am using a riverpod provider class to handle picking of image from gallery. However, once an image is picked, I get the error: PlatformException(multiple_request, Cancelled by a second request null, null). Not sure where a second request is coming from. More importantly, no image is applied to my placeholder (CircleAvartar) due to this unknown cancellation. Here are the two dart files in question and thanks for the help.
imageProvider file:
final myImageProvider =
ChangeNotifierProvider<ImageNotifier>((ref) => ImageNotifier());
class ImageNotifier extends ChangeNotifier {
ImageNotifier() : super();
final file = useState<File?>(null);
final imageFile = useState<XFile?>(null);
final imagePicker = ImagePicker();
Future<void> _pickImage(int type) async {
try {
XFile? userImage = await imagePicker.pickImage(
source: type == 1 ? ImageSource.gallery : ImageSource.camera,
imageQuality: 50,
);
imageFile.value = userImage;
// imageFile.value = XFile(userImage!.path);
} catch (e) {
print(e);
}
notifyListeners();
}
void showPicker(context) {
showModalBottomSheet(
backgroundColor: Theme.of(context).primaryColor,
context: context,
builder: (BuildContext bc) {
return SafeArea(
child: Wrap(
children: [
ListTile(
leading: const Icon(
Icons.photo_library,
color: Colors.white,
),
title: const Text(
'Photo Gallery',
style: TextStyle(fontSize: 22),
),
onTap: () => _pickImage(1),
),
ListTile(
leading: const Icon(
Icons.photo_camera,
color: Colors.white,
),
title: const Text(
'Camera',
style: TextStyle(fontSize: 22),
),
onTap: () => _pickImage(2),
),
ListTile(
leading: const Icon(
Icons.close,
color: Colors.white,
),
title: const Text(
'Cancel',
style: TextStyle(fontSize: 22),
),
onTap: () {
imageFile.value = null;
Navigator.of(context).pop();
},
),
],
),
);
},
);
notifyListeners();
}
AuthScreen dart file:
Widget build(BuildContext context, WidgetRef ref) {
final _passwordController = useTextEditingController();
final _passwordFocusScope = useFocusNode();
final _emailFocusScope = useFocusNode();
final _phoneFocusScope = useFocusNode();
final _confirmFocusScope = useFocusNode();
final _isVisible = useState<bool>(true);
var _authMode = useState<AuthMode>(AuthMode.login);
final imageProviderState = ref.watch(myImageProvider.notifier);
final deviceSize = MediaQuery.of(context).size;
final authMode = ModalRoute.of(context)?.settings.arguments as String;
switch (authMode) {
case 'login':
_authMode.value = AuthMode.login;
break;
case 'register':
_authMode.value = AuthMode.register;
break;
case 'google':
_authMode.value = AuthMode.google;
break;
case 'guest':
_authMode.value = AuthMode.guest;
break;
}
return Scaffold(
body: Stack(
children: [
Padding(
padding: const EdgeInsets.all(8.0),
child: Form(
key: _formKey,
child: SingleChildScrollView(
child: Column(
mainAxisAlignment: MainAxisAlignment.start,
children: [
const SizedBox(
height: 80,
),
Center(
child: _authMode.value == AuthMode.login
? const Text(
'Access Your Account',
style: TextStyle(
fontSize: 25,
),
)
: Row(
children: [
InkWell(
onTap: () =>
imageProviderState.showPicker(context),
// () => ref
// .read(myImageProvider.notifier)
// .showPicker(context),
child: CircleAvatar(
radius: 50,
backgroundImage:
imageProviderState.imageFile.value !=
null
? FileImage(
// File(ref
// .read(imageProvider.notifier)
// .imageFile
// .value!
// .path),
// )
File(imageProviderState
.imageFile.value!.path),

child: imageProviderState.imageFile.value ==

? const Icon(
