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.

  • If you run “flutter doctor” from cli the output show it’s all right or you have some error/warnings? Commented Dec 15, 2018 at 0:53

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.

If the project Gradle version didn't install on your machine, flutter try to download the appropriate version from google server before compile.

So

  1. Ensure your computer is connected to the Internet.
  2. Google restricted access to some of its services in certain countries, such as Iran, Cuba, Sudan, Syria and etc. Therefore, Make sure your system has access to google developer subdomains. (use VPN in restricted countries)
  3. Or Change the project Gradel version on "android\build.gradle -> dependencies" with the installed version number

As shown in the picture above, you should check the plugin version and required gradle version.

For checking plugin version :android-->build.gardle-->build scripts-->dependencies-->calsspath
For cheking required gardle version :android-->gradle-->wrappper-->gradle-wrapper.properties
