Here is the error message with the fix suggestion given by the Flutter SDK.
Go to the Kotlin Gradle Plugin version checkup page, and get the latest version from the page.
The latest version we get is "1.6.21", now you have to update the version code at build.gradle located at android\build.gradle path.
buildscript {
ext.kotlin_version = '2.0.20'
repositories {
google()
mavenCentral()
}
dependencies {
classpath 'com.android.tools.build:gradle:4.1.0'
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
}
}
change the version no. of ext.kotlin_version.
And, in settings.gradle file, update this line:
id "org.jetbrains.kotlin.android" version "2.0.0" apply false
In this way, you can solve "your project requires a newer version of the kotlin gradle plugin" error in Flutter.
