당황해서 이것저것 찾아봤지만

[!] Your project requires a newer version of the Kotlin Gradle plugin.
Find the latest version on https://kotlinlang.org/docs/releases.html#release-details, then
update the
version number of the plugin with id "org.jetbrains.kotlin.android" in the plugins block of
C:\프로젝트명\android\settings.gradle.
Alternatively (if your project was created before Flutter 3.19), update
C:\practice\todo_app\android\build.gradle
ext.kotlin_version = ''
setting.gradle에서 kotlin_version = ''수정해 주란다.

코틀린 최신버전에 맞게 수정
