Failed to build iOS app Error (Xcode): ../../../Developer/flutter/packages/flutter/lib/src/material/data_table.dart:1164:41: Error: Member not found: 'Matrix4.identity'.

Could not build the application for the simulator. Error launching application on iPhone 14 Pro Max.

When i type flutter run the above error occurs on the default application without any configurations. I didn't get why the error occurs.

  • Try command Flutter clean then pub get and run again. – Vishal Zaveri Feb 27 '23 at 03:02
  • i already tried what you suggested but the error keeps on persisting. Its the default app of flutter but this error keeps showing and i didn't even change anything – Reinheart Marl Gatera Golis Feb 27 '23 at 03:24

  • There is an error regarding cocoapods but i dont think it affects my run – Reinheart Marl Gatera Golis Feb 27 '23 at 06:56
  • I think in your system any internet connectivity issue. just verify internet connection before try flutter pub get because on first time all packages will download on your machine. – Vishal Zaveri Feb 27 '23 at 10:19
  • @VishalZaveri my connection is strong. This is the output when i run it on android emulator. Target kernel_snapshot failed: Exception FAILURE: Build failed with an exception. * Where: Script '/Users/lap052user/flutter/packages/flutter_tools/gradle/flutter.gradle' line: 1151 * What went wrong: Execution failed for task ':app:compileFlutterBuildDebug'. > Process 'command '/Users/lap052user/flutter/bin/flutter'' finished with non-zero exit value 1 – Reinheart Marl Gatera Golis Feb 28 '23 at 01:46
  • @VishalZaveri does the error occur due to flutter.gradle? – Reinheart Marl Gatera Golis Feb 28 '23 at 04:01
  • @VishalZaveri i solved the problem using flutter pub cache repair. – Reinheart Marl Gatera Golis Feb 28 '23 at 07:06
  • Ohh great. Just add your answer and close this questions so it will helps to others. Happy coding:) – Vishal Zaveri Feb 28 '23 at 15:59

just run flutter pub cache repair, this error occurs due to corrupted resources etc.
