build.gradle error: Could not create tastk ':generateLockfiles'. in Flutter project but Ap-CodePudding

I have an error in my build.gradle file (android/build.gradle) in my Flutter project. The App is running completely normal but this error is still not looking good to me. Does anyone ever had this problem/error?

Here is my complete build.gradle file:

buildscript {
    ext.kotlin_version = '1.6.10'
    repositories {
        google()
        mavenCentral()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:7.0.2'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath 'com.google.gms:google-services:4.3.13'
    }
}

allprojects {
    repositories {
        google()
        mavenCentral()
    }
}

rootProject.buildDir = '../build'
subprojects {
    project.buildDir = "${rootProject.buildDir}/${project.name}"
    project.evaluationDependsOn(':app')
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

flutter doctor -v Output:

open your android project in android studio file > open > in your flutter project choose android file then rebuild gradle, I have same problem and solved it like this.

You can do flutter clean and flutter pub get and then try to build again.
