I have an existing Temp Mail Android app built with Flutter/Dart and I now need Google AdMob ads woven in properly. Here’s the exact scope: • Banner Ads – load, display, and dispose only on the Home Screen. • Native Advanced Ads – likewise, only on the Home Screen, styled so they blend with my current UI yet remain fully compliant with AdMob and Play Store policies. Technical needs • Clean ad lifecycle handling: initialize, cache, show, fail-retry (single retry per failure), and dispose without memory leaks, ANRs, or unexpected reloads. • Mediation and eCPM optimization settings configured so fill-rate stays high while UX stays smooth. • Any “ads not loading” issues resolved; crashes related to the AdMob SDK must be eliminated. • Code must be written in Dart, using the latest stable Flutter and official Google Mobile Ads plugin. Acceptance criteria 1. No hidden or overlay ads; all placements are clearly visible yet non-intrusive. 2. Test on at least two Android API levels showing zero crashes or policy violations in logcat. 3. Verified impressions, clicks, and eCPM in AdMob dashboard after you hand back a signed release build and the cleaned, well-commented source. I’ll provide current source code, Ad IDs, and UI guidelines as soon as we start. If you’ve shipped production Flutter apps with AdMob before, this should be straightforward—please tell me about one similar integration in your bid.
