Could not resolve com.android.tools.build:gradle:3.2.1. flutter

Question

I am getting this error when I want to run my flutter app. I am using flutter 1.0.0 version and android studio 3.2.1 version.

My emulator is Pixel 2 android 8.1.

I have also used android 9 but it did not work either.

Answer 1

you need to add repository google() to the buildscript dependencies of the root project.

the file might be E:\TUT\flutter\project\myfirstapp\android\build.gradle

right next to the jcenter() repository; which does not serve this dependency.

Answer 2

I was getting the same error until I ran it with internet connection,seemingly it downloaded necessary resources.
