Flutter-me feature

[leoafarias]

This is an idea to improve the process of on-boarding or experimentation from javascript developers. The flow could look something like this
npm install -g flutter-me

• 1. Download correct fvm binary and install
• 2. Clone flutter repository
• 3. Run flutter setup
• 4. Sets flutter command correctly
• 5. Goes into examples/hello_world
• 6. Runs flutter packages get
• 7. Opens the simulator
• 8. flutter run on hello world app
• 9. Installs Flutter vscode extension
• 10. installs Dart vscode extension
• 11. opens vscode

Clean up and improvements

• Wait for simulator to open before running app
• Better feedback and messaging about what is going on
• Display flutter doctor output for next steps
• Allow user to select which project he wants to try
• Check if vscode is installed

I believe this could be an interesting approach to quickly getting someone to play or experiment with flutter and dart.
