| description | Create or update Flet control screenshots and GIFs that are generated from integration tests and shown in docs. Use when working on `sdk/python/packages/flet/integration_tests/examples`, refreshing static or interactive golden screenshots, or replacing old example media images or GIFs with generated test assets. |
Update Flet Control Doc Gifs
Use this skill after the integration test structure is already in place and the task is to capture doc-ready screenshots or interactive GIF states from integration tests.
Workflow
- Locate the example-backed integration test under
sdk/python/packages/flet/integration_tests/examples.
- Prefer extending an existing interaction test instead of creating a second flow test.
- Build the visual sequence with deterministic states:
- set
page.enable_screenshots = True
- set
theme_mode when visuals matter
- set fixed page size before screenshots
- prefer finding controls by visible text or other stable user-facing content; add a
key only when there is no reliable human-facing locator
- call
pump_and_settle() after each interaction
- Capture only states that are visually meaningful:
- before interaction
- hover state
- popup/menu/dialog open
- reopened state that proves persistence
- single static screenshots when one frame is enough for docs
- do not keep screenshots taken after a click if the UI closes and the state is not visible
- Use
assert_screenshot(...) for regular golden screenshots and create_gif([...], "<flow_name>", duration=...) only when the docs benefit from an animated flow.
- Prefer storing only asserted or docs-facing states as named screenshots; keep intermediate hover/click frames in memory and pass them directly to
create_gif(...) when they do not need standalone golden files.
- Update docs to use the generated screenshot or GIF, not an old media asset from
examples/.../media, when the integration-test asset is now the better docs artifact.
- Update docs references to point at the intended generated screenshot or GIF path, but do not copy generated assets into
website/static/docs/test-images/... as part of this workflow.
Naming
- Use short screenshot names that describe visible states, for example
before_click, hover_popup, popup_open, checked_item_reopened.
- Use one flow GIF name per control/example, for example
app_bar_flow.
- Use descriptive static screenshot names when the asset is docs-facing, for example
image_for_docs, popup_open, or checked_item_reopened.
- Give the integration test a behavior-based name such as
test_actions_and_popup_menu; avoid placeholder names like test_basic when the test covers a specific flow.
- Keep screenshot names stable because they become golden filenames.
Docs Update Rules
- Control docs usually point to generated assets through
frontMatter.example_images.
- If a docs page still has
example_images pointing at example media instead of generated test images, update that front matter first so the page has a single source of truth for screenshots and GIFs.
- When a docs page has multiple example sections, add the generated screenshot or GIF directly under the matching
CodeExample block so each visual stays paired with the example it demonstrates.
- If a docs page still uses
frontMatter.example_media + '/old.png' or frontMatter.example_media + '/old.gif', replace it with frontMatter.example_images + '/<asset>' when the generated integration-test asset is the new source of truth.
- Generated screenshots and GIFs from integration tests are commonly stored at
sdk/python/packages/flet/integration_tests/examples/.../golden/macos/<control>/.
- Do not copy generated screenshots or GIFs into
website/static/docs/test-images/... as part of this skill. Keep the work limited to tests and docs references unless the user explicitly asks for a copy.
Verification Checklist
- The interaction test still reflects the example behavior.
- Every screenshot included in a GIF is visibly different and useful.
- The GIF duration is intentional; prefer shorter loops for hover/click flows unless the interaction needs more time.
- The docs front matter points to the generated test-images location rather than stale example media paths.
- The docs page references the new screenshot or GIF path.
- The generated screenshot or GIF exists in the integration-test golden directory at the path implied by the test names.
- Remove or stop referencing obsolete media screenshots or GIFs only when the new generated asset fully replaces them.
