❗️ What is actually happening?

Recently I downloaded some flutter project from github.

When I ran it, I got an error like below.

🛠 Issue Solved

This error is caused by incompatibility with Flutter version 2.10.1 and Kotlin version.

To solve this error, you need to change ext.kotlin_version from 1.3.50 to 1.6.10 in android/build.gradle.

buildscript {
    ext.kotlin_version = '1.6.10' //change this line.
    repositories {
        google()
        mavenCentral()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:4.1.0'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}
