I want to generate apk in vs code by command flutter build apk, So :

  1. I install Android Studio and Android SDK in path C:Android_SDK.
  2. I execute command flutter config --android-sdk "c:Android_SDK" in vscode terminal
  3. I Restart vscode.
  4. I defined enviroment variable ANDROID_HOME with value C:Android_SDK.
  5. I execute command flutter build apk in terminal.
    but returns this error :

  1. Just type this in your terminal:

    flutter config --android-sdk path of your sdk
    

    For example:

    flutter config --android-sdk c:androidsdk

  2. You can install android studio,
    Then it will ask for sdk path folder, since you don’t have any, selected an empty folder and click on next.
    Android studio will download sdk for you.
