This talk explores the things I learned while building and launching my Flutter Tips app on the App Store and Play Store, including: how to use a GitHub repo as a free data source for the app, how to pre-process Markdown content to be shown in the UI, offline mode and caching with Drift & Riverpod, the importance of analytics and error monitoring with tools like Sentry and Mixpanel, some obstacles I encountered when publishing the app, and how the overall launch went.
