I using Macbook Air mid 2013 for flutter without Xcode . Why I can't run in android emulator

Launching lib/main.dart on Android SDK built for x86 in debug mode...
lib/main.dart:1
FAILURE: Build failed with an exception.
* What went wrong:
A problem was found with the configuration of task ':app:processDebugResources' (type 'LinkApplicationAndroidResourcesTask').
- In plugin 'com.android.internal.version-check' type 'com.android.build.gradle.internal.res.LinkApplicationAndroidResourcesTask' property 'androidJarInput.androidJar' specifies file '/Users/macbook/Library/Android/sdk/platforms/android-31/android.jar' which doesn't exist.
Reason: An input file was expected to be present but it doesn't exist.
Possible solutions:
1. Make sure the file exists before the task is called.
2. Make sure that the task which produces the file is declared as an input.
Please refer to https://docs.gradle.org/7.4/userguide/validation_problems.html#input_file_does_not_exist for more details about this problem.

I saw other people talk about this here but the solution that worked for them didn't work for me.
Here are the things I've tried:
./gralew clean or./gradlew build
/flutter clean
reinstalling flutter and android studio from scratch.
deleting the gradle files and the build files.
switching to another laptop.
I will be very grateful if you guys can help me.
Best Regards,

Peace!

Open Android Studio make sure you have the latest version installed, and everything is updated then go ahead and open the Flutter project and trying building it from Android Studio

I found the similar error but for me is missing of androidmanifest.xml and I have fixed it
For me I have deleted the android folder and run command "flutter create ."
then I got another of errors about "SdkMinVersion" and "Flutter multidex handling is disabled." and fixed it step by step
Anyway I have found this solution after I have fixed and hope it will help you
--> changing gradle version as the link below

I think it is gradle issue. I am using flutter v1.12.13+hotfix.6

Fixed this problem. There was a permission issue on .gradle directory, it was readonly . So changing permission solves this issue.
