I found a solution! Go to your flutter folder. After you need to find flutter.gradle. On my PC: C:\src\flutter\packages\flutter_tools\gradle Open flutter.gradle with note or notepad and change buildscript from this:

 repositories {
   jcenter()
    maven {
        url 'https://dl.google.com/dl/android/maven2'
    }    
}

to this:

 repositories {
    maven {
        url 'https://dl.google.com/dl/android/maven2'
    } 
    jcenter()
}
