Could not build the precompiled application for the device.
It appears that your application still contains the default signing identifier.
Try replacing 'com.example' with your signing id in Xcode:
open ios/Runner.xcworkspace
I thought its svg error thats why i changed in the pubspec.yaml from flutter_svg: ^0.17.4 to flutter_svg: ^0.18.0 then i get this error.But if i use flutter_svg: ^0.17.4 then i get following error:
Exception has occurred. FlutterError (Unable to load asset: imageurl/fs.png
I also tried to use this websafe_svg: ^1.1.4 package but still same error.Can you help me out what can i do for resolve this problem?
Thanks In Advance.

Answer 1

Sorry everybody for wasting your time to read my stupid question.Let me clear what stupidity i have done. For latest xcode (In my case xcode 12) i used cupertino_icons: ^0.1.0 in pubspec.yaml file, that is why i was getting dependencies error for flutter_svg package.It should be cupertino_icons: ^0.1.3 and flutter_svg: ^0.18.0
Second stupidity is was trying to load image using image.asset() thats why even though i used flutter_svg: ^0.18.0 but still i was getting Exception has occurred.Because it was searching that image url in my application asset folder.FlutterError (Unable to load asset: this error. So i changed it to FadeInImage.assetNetwork
Hope my answer will help someone if any problem occur like mine.
