Flutter Monetization Stats Popup

I already track total views, video count and the usual Top-10 lists in my Flutter app. Now I want one more screen-wide popup, launched only when the user taps a new button or icon, that tells two things:

• how long my YouTube channel has been monetized, shown in plain years and also in years with two decimals
• how many calendar days it took me to make the very first $1

The popup must respect the same dynamic date filters I use elsewhere: 1 month, 3 months, 6 months, 1 year, 2 years, 3 years, 5 years and lifetime. Selecting a period immediately refreshes the two figures above.

All data should be pulled and processed inside a Google Cloud project (the one you create specifically for this task). When you are done, share that project with my Google account so I can inspect the cloud functions, API keys and IAM roles directly.

Deliverables
• Updated Flutter source with the new interactive popup wired into the existing filter menu
• The Google Cloud Console project containing any functions, scheduled jobs or APIs you used
• A short read-me outlining service-to-service credentials and where to paste my own keys

If the app builds successfully and the numbers match those in YouTube Studio for each timeframe, I will consider the work complete.
