강의에서 말하는데로 따라서 했는데 run without debugging 했을 때 오류가 뜨고 앱화면이 안뜨네요.

import 'package:flutter/material.dart';


void main() {
  runApp(MyApp());
}


class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);


  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      debugShowCheckedModeBanner: false,
      home: Scaffold(
        appBar: AppBar(),
      ),
    );
  }
}



Launching lib\main.dart on sdk gphone64 x86 64 in debug mode...


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 'C:\Users\Suppy\AppData\Local\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.
* Try:

> Run with --info or --debug option to get more log output.
> Run with --scan to get full insights.
