According to the stack, all of them from the flutter framework. I have no idea to find out where causes this error in my code.
I guess it must a wrong stage during widget rendering.
Can you give me some idea?
My pubspec.yaml like this:
environment:
sdk: ">=2.10.0 <3.0.0"
flutter: ^3.3.10
According to the page tracking info, I finally find out this issue:
I use routes#showGeneralDialog to display a widget with wrong width.
i am trying to display the image that I am getting as a response from API.
below is the code for displaying the image -:
String ProfilePic;
CircleAvatar(
radius: 80,
backgroundImage:
ProfilePic != null ?
NetworkImage('$ProfilePic'):
// AssetImage('$ProfilePic') :
AssetImage('assets/favicon.png'),
),
As a response, I am getting this data from API -: I/flutter ( 4230): pexels-lisa-1107717.jpg
and when I use it I get following error -:

Image provider: NetworkImage("null", scale: 1.0)
Image key: NetworkImage("null", scale: 1.0)
====================================================================================================
i have used network image but still, I am not able to display the image. i have tried other solutions too but nothing seems to work.
can anyone help me with displaying this?
Your check is wrong it should be this way
ProfilePic != null ? NetworkImage('$ProfilePic'):AssetImage('assets/favicon.png'),
I have tried many ways to solve it in the last 3 days, but nothing worked. Has anyone experienced it too?

I am tring to install and setup flutter by followig way
1. I downloaded flutter and unzip
2. Added path of flutter and bin folder in environment variable
3. Fire command flutter doctor
Then dart has been downloaded via command line and then i got error
Oops; flutter has exited unexpectedly: "Invalid argument(s): Cannot find executable for where.". Unable to generate crash report due to secondary error: Invalid argument(s): Cannot find executable for where.

I solved the issue by following 3 steps,
first step:- you need to disabled your virus guard,
second step:- you should remove cache folder entirely (it is located in ex:- 'C:\flutter\bin\cache')
Run 'Flutter Doctor' which would download all artifacts again
You have to install git and then restart your editors and your device
How can I resolve the problem as below ?
I run my application normally, it's run well.
But when I've set break point, then tried to perform debugging my code.
It always shows the error messages which do not come from my code, debugger is interrupted as well.
Unhandled exception:
NoSuchMethodError: The getter 'cls' was called on null.

My code:
main.dart
void main() async {
Flame.images.loadAll(<String>[
'level0.jpg'
]);
Util flameUtil = Util();
await flameUtil.fullScreen();
await flameUtil.setOrientation(DeviceOrientation.portraitUp);
MyGame game = MyGame ();
runApp(game.widget);
....
mygame.dart:
......
MyGame() {
sprite = Sprite('level0.jpg');// Break point
}
.............
note:
I am using Android studio 3.1
