Development Enviroment

Virtual Devices

Virtual devices can be created by opening the command-palette and selecting Flutter: Select Device, and selecting create android emulator. However, the performance is not accurate and convenience is limited, therefore I recommend using a physical device.

Physical Devices

Android devices can be use for running builds by enabling USB debugging from Android developer settings, this is done by:

1. Open settings and navigate to About Phone
2. Tab on the build number 7 times until a confirmation message appear
3. Then enter Developer Options and enable USB debugging
4. Plug the phone into the computer with USB connection

Now when selecting VSCode/command-palette/Flutter: Select Device, the identifier of the phone will appear.

warning

If running Flutter: Select Device does not show your physical device, try revoking the USB Debugging and disconnect the device. Then reconnect the device and check remember device when verifying.

Compiling and Running

With everything setup and a Flutter: new project created, the code can now be compiled and ran with the device selected. Now simply clicking F5 (VSCode's debug mode) will run the command of flutter run --debug and a counter app will be visible on your device. This is JIT compiled, and can be hot-reloaded. If you want a release build use the --release flag instead, the profile mode is a bit more complex, refer to Flutter documentation for more detail.
