31.3 Flutter App Creation

20220319 To begin a new app simply create a folder of the name that you want to use for the app, and then ask flutter to create the app skeleton. Here we create an app called button:

mkdir button
cd button
flutter create .

A skeleton and fully functional dart program is found in lib/main.dart. The file pubspec.yaml holds general information about the app (name, description, publish_to, and version), the development environment, dependencies (including dev_dependencies required just for development), and Flutter configurations.

If your Android device is connected to the computer then you can build, install, and run the app on the device with run:

flutter run

Check what devices are available with:

flutter devices

To build for and run on a Linux desktop see Section 31.16.
