InterstitialAd

Displays a full-screen interstitial ad.

Note

Each instance is allowed to be shown (using show()) only once. To show another ad, create a new instance. Reusing an already-shown instance will result in errors or unexpected behavior.

Test IDs

AdMob provides unit IDs for testing purposes. Set [unit_id][flet_ads.interstitial_ad.InterstitialAd.unit_id] to the appropriate value based on the platform you're testing on:

  • Android: "ca-app-pub-3940256099942544/1033173712"
  • iOS: "ca-app-pub-3940256099942544/4411468910"

Remember to replace them in production.

Raises:

  • FletUnsupportedPlatformException

    When using this control on a web and/or non-mobile platform.

Inherits: Service, BaseAd

Methods

  • show

    Present the loaded interstitial ad as a full-screen overlay.
