showSliderAdView method

Future<void>? showSliderAdView({ required BuildContext context, required Map<String, dynamic> adData, int? width, int? height, int? x, int? y, String? adLabelText, String? adLabelAlignment, void onAdClicked(Map? ad)?, void onAdAppeared(Map? ad, String? trackingId)?, required OsmosConfig config, })

Displays the slider ad and starts listening for ad events.

This method triggers the native slider ad view with the given parameters and sets up a listener to handle adClicked and adAppeared events.

Parameters:

• adData (Map<String, dynamic>): Required ad metadata to display the ad.
• width (int?): Optional width of the slider ad view in pixels.
• height (int?): Optional height of the slider ad view in pixels.
• x (int?): Optional X-axis coordinate for ad positioning.
• y (int?): Optional Y-axis coordinate for ad positioning.
• onAdClicked (void Function(Map? ad)?): Optional callback triggered when the ad is clicked.
• onAdAppeared (void Function(Map? ad, String? trackingId)?): Optional callback triggered when the ad appears.
• config (OsmosConfig): Required OSMOS SDK configuration.

Returns: Future<void>.
