I am trying run flutter app via Android Studio 3.2 but not working.

[✓] Android toolchain - develop for Android devices (Android SDK 28.0.3)
[✓] Android Studio (version 3.2)

buildscript {
    repositories {
        google()
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.2'
    }
}

allprojects {
    repositories {

rootProject.buildDir = '../build'
subprojects {
    project.buildDir = "${rootProject.buildDir}/${project.name}"

yes since a few weeks google() has to be the first in the project build.gradle since jcenter does not have copies of the libraries anymore — Christian, Nov 02 '18 at 09:27

I don'to know why but in app/build.gradle at line 25 I have

apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"

So I had to change file in flutter library! in file flutter.gradle I had

buildscript {
    repositories {
        jcenter() 
        maven {
            url 'https://dl.google.com/dl/android/maven2'
        }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.2'
    }
}

change to this

buildscript {
    repositories {
        maven {
            url 'https://dl.google.com/dl/android/maven2'
        }
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.2'
    }
}

So I dont know why I have to changing library files. Do you know why? Thank you

Basically it's a problem with flutter, but the root cause is not flutter. Check this answer, you can easily make it work by switch to the master channel.
