I am following a tutorial of adding a Banner Ad. But for me it gives this error.
The getter 'testAdUnitID' isn't defined for the type 'BannerAd'.
Is testAdUnitID is deprecated or something? What's the way out?
My code is:
void _initBannerAd() {
_bannerAd = BannerAd(
size: AdSize.banner,
adUnitId: BannerAd.testAdUnitID,
listener: BannerAdListener(),
request: AdRequest(),
);
}
Here is the screenshot:
