adpluga_flutter

Added

• alt_text on the served creative, announced in place of the image. An ad is never decorative — it carries meaning and opens a destination — so rendering it unlabelled left the tap target with no accessible name at all, failing WCAG 2.2 SC 1.1.1 and SC 2.4.4 (both level A). Where the advertiser wrote no alternative text the renderer falls back to the creative's title, and a carousel card with no copy of its own inherits the ad's label.

Fixed

• A slot that failed to fill stayed blank for the rest of the session. Only the success path armed the next attempt, so a transient miss — or a widget that mounted before the SDK was initialised — cost the publisher that slot until the view was recreated. Every failure path now schedules another attempt, backing off exponentially from the client's cadence floor up to five minutes. Retry is independent of the slot's rotation cadence, which is off by default: tying recovery to rotation is what made a single miss permanent.

Fixed

• Impressions are no longer counted for a slot the host is not painting. The viewability check was pure geometry, so a banner on a hidden IndexedStack page or inside a collapsed viewport kept a valid rect and billed as fully viewable. It now consults Visibility.of and every ancestor paint clip, matching what the Android and iOS SDKs already did.
• Tapping an image creative now opens the advertiser destination. HTML and video creatives always did; image ones reported the click and went nowhere, so the advertiser paid for a tap that never arrived.
• initialize with a different publisher key now fails instead of quietly returning the existing instance. Rotating a key revokes the previous one at once, so the silent path left an app serving with a dead key. The same key stays idempotent; call destroy() first to re-initialize deliberately.
• conversion() sent type/value; the API reads conv_type/value_cents, so both were dropped. The old argument names still work, deprecated.

Changed

• Without an explicit width/height, the banner now adopts the served creative's aspect ratio instead of pinning the box to its pixel size, so the fit is exact and a creative wider than the screen no longer overflows. A host that passes both dimensions still wins.
• endpoint accepts null to mean "use the default", and kDefaultEndpoint is exported, so a host reading the endpoint from configuration no longer has to hardcode an AdPluga hostname.

Added

• AdPlugaCarousel renders type=carousel decks in a PageView. The deck is one advertiser and one auction: every card reports the same click and no card triggers another serve, so swiping costs no decisions and no extra impression.
• Slide model and Ad.slides, parsed in the order the advertiser arranged; a slide without a creative is dropped rather than drawn blank.

Changed

• A scheduled rotation now backs off while the reader is swiping the deck and resumes one full cadence after the last swipe.
• A slot cadence below the client floor is raised to it instead of being ignored, so a slot set to 15s rotates every 15s on a pk_test_ key and every 30s on a live one — it never stops rotating.

Added

• Slot rotation: banners now re-serve on the cadence the publisher configures for the slot (refresh_after_seconds on the serve response). Long-lived app screens no longer show a single frozen creative — the mobile equivalent of a web page reload.
• Rotation is gated so it cannot waste the publisher's budget or produce non-viewable impressions: it only fires while the ad meets the IAB pixel threshold and the app is in the foreground, is floored at 30s (kMinRefreshSeconds), and the timer is cancelled on dispose and while backgrounded.
• Each rotation sends its index (rq) so refreshed impressions stay segregable from the initial render, as the MRC guidelines require.

Added

• Test-mode badge: creatives served by a pk_test_ (sandbox) key now render a small non-interactive "TEST" marker at the top-left of every ad surface (banner, native, HTML, video, interstitial, rewarded). Driven by the new test boolean on the serve response ad object (Ad.isTest). The badge is wrapped in IgnorePointer so it never intercepts taps.

Added

• Audio and video_rewarded ad kinds render via AdPlugaVideo widget in AdPlugaBanner, enabling autoplay for all video/audio formats.

Fixed

• QuartileFirer now resolves relative ping URLs against the SDK endpoint, fixing quartile tracking when the backend returns relative paths.
• Fixed AdPluga.maybeInstance?.endpoint → AdPluga.maybeInstance?.config.endpoint in AdPlugaVideo widget (2 occurrences).
