How it works¶

flet-review is a Flet extension made of two halves that ship in the same Python package:

Python — InAppReview (src/flet_review/flet_review.py), a ft.Service registered as control type "InAppReview".
Flutter — the flet_review Dart package (src/flutter/flet_review), which depends on flet ^1.0.0 and in_app_review ^2.0.9.

Call flow¶

    participant App as Your Flet app
    participant Py as InAppReview (Python)
    participant Ext as Extension (Dart)
    participant Svc as InAppReviewService (Dart)
    participant Plugin as in_app_review

    App->>Py: await review.request_review()
    Py->>Ext: control "InAppReview" added
    Ext->>Svc: createService()
    Svc->>Svc: init(): addInvokeMethodListener
    Py->>Svc: invoke "request_review"
    Svc->>Plugin: InAppReview.instance.requestReview()
    Plugin-->>Svc: done
    Svc-->>Py: null
    Py-->>App: None

Method mapping¶

Python method	Invoked name	Plugin call	Returns
`is_available()`	`is_available`	`isAvailable()`	`bool`
`request_review()`	`request_review`	`requestReview()`	`None`
`open_store_listing(app_store_id)`	`open_store_listing`	`openStoreListing(appStoreId: ...)`	`None`

Any other method name throws Exception("Unknown InAppReview method: <name>"). When the control is removed, dispose() unregisters the listener.
