I am using "mobile_number(version - 1.0.3)" plugin to get mobile number in flutter app, am running in original device but i couldn't get mobile number.instead of errors i can get mobile number as null along with other sim details as shown in screen shot.
help me to resolve this problem, i had just copy pasted the example given by plugin that is the code
plugin link
It says:
Note: If the mobile number is not pre-exist on sim card it will not return te phone number.
I think mobile number does not pre-exist on the SIM if the SIM is not original (i.e. replaced)
If the phone number isn't stored on the sim (aka null), then you can't get it from anywhere else, in that case you probably want to forward the user to a different page where they can type the phone number using TextField and then store it somewhere
Use Mobile_number package to get mobile number and other details. For example
import 'dart:async';
import 'package:flutter/foundation.dart';
import 'package:flutter/material.dart';
import 'package:flutter/services.dart';
import 'package:mobile_number/mobile_number.dart';
void main() => runApp(MyApp());
class MyApp extends StatefulWidget {
#override
_MyAppState createState() => _MyAppState();
}
class _MyAppState extends State<MyApp> {
String _mobileNumber = '';
List<SimCard> _simCard = <SimCard>[];
#override
void initState() {
super.initState();
MobileNumber.listenPhonePermission((isPermissionGranted) {
if (isPermissionGranted) {
initMobileNumberState();
} else {}
});
initMobileNumberState();
}
// Platform messages are asynchronous, so we initialize in an async method.
Future<void> initMobileNumberState() async {
if (!await MobileNumber.hasPhonePermission) {
await MobileNumber.requestPhonePermission;
return;
}
String mobileNumber = '';
// Platform messages may fail, so we use a try/catch PlatformException.
try {
mobileNumber = (await MobileNumber.mobileNumber)!;
_simCard = (await MobileNumber.getSimCards)!;
} on PlatformException catch (e) {
debugPrint("Failed to get mobile number because of '${e.message}'");
}
// If the widget was removed from the tree while the asynchronous platform
// message was in flight, we want to discard the reply rather than calling
// setState to update our non-existent appearance.
if (!mounted) return;
setState(() {
_mobileNumber = mobileNumber;
});
}
Widget fillCards() {
List<Widget> widgets = _simCard
.map((SimCard sim) => Text(
'Sim Card Number: (${sim.countryPhonePrefix}) - ${sim.number}\nCarrier Name: ${sim.carrierName}\nCountry Iso: ${sim.countryIso}\nDisplay Name: ${sim.displayName}\nSim Slot Index: ${sim.slotIndex}\n\n'))
.toList();
return Column(children: widgets);
}
#override
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
appBar: AppBar(
title: const Text('Plugin example app'),
),
body: Center(
child: Column(
children: <Widget>[
Text('Running on: $_mobileNumber\n'),
fillCards()
],
),
),
),
);
}
}

I'm creating an app in Flutter to store any type of media, imagem, video, pdfs, etc. And I want to be able to receive share intents from other apps in the easiest way possible for the user.
So, my idea is to be able to simply receive the media without needing to open the app for the user to input something, they should simply select my app to receive the media and continue using the "source" app. Is that possible in flutter?
this should work very well based on your requirement, receive_sharing_intent, just following the setup for android & ios and try the example:
import 'package:flutter/material.dart';
import 'dart:async';
import 'package:receive_sharing_intent/receive_sharing_intent.dart';
void main() => runApp(MyApp());
class MyApp extends StatefulWidget {
#override
_MyAppState createState() => _MyAppState();
}
class _MyAppState extends State<MyApp> {
StreamSubscription _intentDataStreamSubscription;
List<SharedMediaFile> _sharedFiles;
String _sharedText;
#override
void initState() {
super.initState();
// For sharing images coming from outside the app while the app is in the memory
_intentDataStreamSubscription =
ReceiveSharingIntent.getMediaStream().listen((List<SharedMediaFile> value) {
setState(() {
print("Shared:" + (_sharedFiles?.map((f)=> f.path)?.join(",") ?? ""));
_sharedFiles = value;
});
}, onError: (err) {
print("getIntentDataStream error: $err");
});
// For sharing images coming from outside the app while the app is closed
ReceiveSharingIntent.getInitialMedia().then((List<SharedMediaFile> value) {
setState(() {
_sharedFiles = value;
});
});
// For sharing or opening urls/text coming from outside the app while the app is in the memory
_intentDataStreamSubscription =
ReceiveSharingIntent.getTextStream().listen((String value) {
setState(() {
_sharedText = value;
});
}, onError: (err) {
print("getLinkStream error: $err");
});
// For sharing or opening urls/text coming from outside the app while the app is closed
ReceiveSharingIntent.getInitialText().then((String value) {
setState(() {
_sharedText = value;
});
});
}
#override
void dispose() {
_intentDataStreamSubscription.cancel();
super.dispose();
}
#override
Widget build(BuildContext context) {
const textStyleBold = const TextStyle(fontWeight: FontWeight.bold);
return MaterialApp(
home: Scaffold(
appBar: AppBar(
title: const Text('Plugin example app'),
),
body: Center(
child: Column(
children: <Widget>[
Text("Shared files:", style: textStyleBold),
Text(_sharedFiles?.map((f)=> f.path)?.join(",") ?? ""),
SizedBox(height: 100),
Text("Shared urls/text:", style: textStyleBold),
Text(_sharedText ?? "")
],
),
),
),
);
}
}
Using Receive Sharing intent package, you can receive text & media files in closed as well as opened application.
Below code snippet to receive intent in closed application,
// For sharing images coming from outside the app while the app is closed
ReceiveSharingIntent.getInitialMedia().then((List<SharedMediaFile> value) {
setState(() {
_sharedFiles = value;
});
});
You can go through this link for further understanding on how to receive intent in already opened & closed application.
I have a login screen which uses phone authentication for creating account.
I have used Firebase Phone auth for login and also have stored one number for testing purpose.
But don't know how to pass the number and OTP to generate Pre Launch Report.
They are asking for Username, Username Resource ID, Password , Password Resource ID.
Where to find Resource ID for username and password fields in flutter code.
In the Google play console at the bottom of the left
Click on App content
Click on App access
Click on manage
Click on add new instructions
Add your all details here it should be test accounts
Try this :

I need help regarding the images in my app. I would like to add 3 buttons for:
Download
Save as
Change phone wallpaper
I'm not using urls. I already have my images in an assets repository.
Do you have any idea how I can do that? Thank you.
You can copy paste run full code below
You can use package https://pub.dev/packages/wallpaper_manager
You can directly set wallpaper with image in assets
Example code's assets image path is "assets/tmp1.jpg"
code snippet
result = await WallpaperManager.setWallpaperFromAsset(
assetPath, WallpaperManager.HOME_SCREEN);

I am using package of location and google maps flutter in my screen and I want to detect wether user using fake gps or not.. Is there a package that can detect mock location in flutter that available in android and ios? I have tried using TrustFall package but my app always close unexpectedly.. is there another way to detect mock location in flutter?
Use Geolocator and check the Position object's isMocked property.
you can use TrustLocation
permissions:
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
usage :
import 'package:trust_location/trust_location.dart';
/* Assuming in an async function */
/// query the current location.
LatLongPosition position = await TrustLocation.getLatLong;
/// check mock location on Android device.
bool isMockLocation = await TrustLocation.isMockLocation;
using steam:
// input seconds into parameter for getting location with repeating by timer.
// this example set to 5 seconds.
TrustLocation.start(5);
/// the stream getter where others can listen to.
TrustLocation.onChange.listen((values) =>
print('${values.latitude} ${values.longitude} ${values.isMockLocation}')
);
/// stop repeating by timer
TrustLocation.stop();
Example:
import 'package:flutter/material.dart';
import 'dart:async';
import 'package:flutter/services.dart';
import 'package:trust_location/trust_location.dart';
import 'package:location_permissions/location_permissions.dart';
void main() => runApp(MyApp());
class MyApp extends StatefulWidget {
#override
_MyAppState createState() => _MyAppState();
}
class _MyAppState extends State<MyApp> {
String _latitude;
String _longitude;
bool _isMockLocation;
/// initialize state.
#override
void initState() {
super.initState();
requestLocationPermission();
// input seconds into parameter for getting location with repeating by timer.
// this example set to 5 seconds.
TrustLocation.start(5);
getLocation();
}
/// get location method, use a try/catch PlatformException.
Future<void> getLocation() async {
try {
TrustLocation.onChange.listen((values) => setState(() {
_latitude = values.latitude;
_longitude = values.longitude;
_isMockLocation = values.isMockLocation;
}));
} on PlatformException catch (e) {
print('PlatformException $e');
}
}
/// request location permission at runtime.
void requestLocationPermission() async {
PermissionStatus permission =
await LocationPermissions().requestPermissions();
print('permissions: $permission');
}
#override
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
appBar: AppBar(
title: const Text('Trust Location Plugin'),
),
body: Padding(
padding: const EdgeInsets.all(20.0),
child: Center(
child: Column(
children: <Widget>[
Text('Mock Location: $_isMockLocation'),
Text('Latitude: $_latitude, Longitude: $_longitude'),
],
)),
),
),
);
}
}

I think better to use safe_device. It's working on both Android and IOS
