What actually makes a Flutter app fast? And why is this topic so often surrounded by myths, holy wars, and fake silver bullets? In this talk, I won’t just repeat well-known performance tips. Instead, we’ll approach performance like real engineers through measurement and analysis. These two words will be our Polar Star to find out when, what, and how to optimize. We'll explore real examples: When const truly helps — and when it makes no difference; How pressing a button with an empty handler can eat up your entire frame budget; Why the same tool can either save or destroy your app’s performance; How to detect invisible resource drains that silently sabotage your UI. Performance isn’t about magic. It’s about understanding how Flutter really works, and helping it do its job efficiently.
