Flutter run doesn't work

[klausgreiner]

I had to recreate my project and paste the files into it and it worked.
FAILURE: Build failed with an exception.

• What went wrong:
  Could not determine the dependencies of task ':app:compileDebugJavaWithJavac'.

Failed to install the following SDK components:
platforms;android-29 Android SDK Platform 29
The SDK directory is not writable (C:\Program Files (x86)\Android\android-sdk)

Make sure these are the steps you follow while you pull a project from GitHub

1. Import the project form GitHub using the repo link and do not open it immediately

2. Close all the existing projects and now choose open an existing project in Android Studio

3. Once opened, first head to the main.dart where you would get a prompt asking if you want Dart support enabled

4. After you accept it, another prompet follows which is the get dependencies option which you will need to accept

5. Given the required time for things to load, you would get a project successfully built without any errors.
