I am working on a app which has multiple screens. Camera image capturing screen is never directly called by main screen instead of sub screens. Though My camera picker code works perfectly as an individual flutter project when I put it in main file and execute. But when I do the same by using a stateful widget class and calling it via Navigator push, It just doesn't respond. The camera opening part.
Code for the screen that invokes camera screen
import 'package:carryon/luggageupdatepage.dart';
import 'package:carryon/scannerscreen.dart';
import 'package:flutter/material.dart';
import 'allvalues.dart';
import 'login_screen.dart';
import 'welcome_screen.dart';
import 'auth.dart';
class DetailsPage extends StatelessWidget {
@override
Widget build(BuildContext context) {
return Detailspage();
}
}
class Detailspage extends StatefulWidget {
@override
_DetailspageState createState() => _DetailspageState();
}
class _DetailspageState extends State<Detailspage>
with TickerProviderStateMixin{
final AuthServices _auth=AuthServices();
void _showDialog() {
// flutter defined function
showDialog(
context: context,
builder: (BuildContext context) {
// return object of type Dialog
return AlertDialog(
title: Text("Invalid PNR",
style: TextStyle(fontSize: 14),),
content: Text(
"Please neter a valid PNR number.",
style: TextStyle(fontSize: 12,),),
actions: <Widget>[
// usually buttons at the bottom of the dialog
new FlatButton(
child: new Text("Close"),
onPressed: () {
Navigator.of(context).pop();
},
),
],
);
},
);
}
AnimationController controller;
Animation<double> animation;
@override
initState() {
super.initState();
controller = AnimationController(
duration: const Duration(seconds: 3), vsync: this);
animation = CurvedAnimation(parent: controller, curve: Curves.easeIn);
controller.forward();
}
@override
Widget build(BuildContext context) {
return FadeTransition(
opacity: animation,
child: Scaffold(
resizeToAvoidBottomInset: false,
backgroundColor: Background_Color,
appBar: AppBar(
actions: <Widget>[
FlatButton.icon(onPressed: ()async{
await _auth.signOut();
Navigator.push(context,
MaterialPageRoute(
builder: (context)=>CarryOn()),);
},
icon: Icon(Icons.perm_identity), label: Text('Logout'))
],
title: Text(
'Flight CheckIn',
style: LoginScreenTextStyle.copyWith(fontSize: 20),
),
),
body: Column(
children: <Widget>[
SizedBox(height: 30,),
Container(
width: double.infinity,
color: Colors.green,
child: Text(
'Your Flight ${userdetails.FlightName} from ${userdetails.Departure_Destination} to ${userdetails.Arrival_Destination} on ${userdetails.Departure_Date} is on time. Kindly report one hour prior to boarding time.',

child: DecoratedBox(
decoration:ShapeDecoration(shape:roundedrectangle, color:Button_Color),
child: OutlineButton(
color:Button_Color,
borderSide: BorderSide(color:Colors.white,),
shape: roundedrectangle,
child: Center(child: Text('My Luggage Status')),
onPressed: ()
{
Navigator.push(context,
MaterialPageRoute(
builder: (context)=>LuggageUpdates()),);
},
),
),
),
SizedBox(height: 30,),
Container(
height: 50,width:250,
child: DecoratedBox(

onPressed: ()
{
Navigator.push(context,
MaterialPageRoute(
builder: (context)=>MyApp()),);
},
),
),
),
],
),
),
);
}
}
code I used to execute for the camera screen:
import 'package:flutter/material.dart';
import 'dart:io';
import 'package:image_picker/image_picker.dart';
class MyApp extends StatefulWidget {
@override
_MyAppState createState() => _MyAppState();
}
class _MyAppState extends State<MyApp> {
File _image;
Future getImage(bool isCamera)
async{
File image;
if(isCamera)
{
image=await ImagePicker.pickImage(source: ImageSource.camera);
print('camera chale to sahi');
}
else
image=await ImagePicker.pickImage(source: ImageSource.gallery);
setState(() {
_image=image;
});
}
@override
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
appBar: AppBar(
title: Text('Image Pick Demo',),
),
body: Column(
children: <Widget>[
IconButton(
icon: Icon(Icons.insert_drive_file),
onPressed:(){
getImage(false);
},
),
SizedBox(height: 10,),
IconButton(
icon: Icon(Icons.camera_alt),
onPressed: (){getImage(true);},
),
_image==null?Container():Image.file(_image,height: 300,width: 300,),
],
),
),
);
}
}
The exact same code works when run directly by main.dart, so there's some blunder I am doing in invoking the camera_screen.dart file.
