Building and running

Flet extensions include native Flutter code, so the extension must be included in the client before the viewer can render.

Build the example

cd examples/flet_image_viewer_example
flet build windows
flet run

Replace windows with another supported target such as macos, linux, apk, or ipa.

Rebuild after changing the extension's Dart code. Python-only changes can be run again without rebuilding the native extension.
