Flutter: The Wizards of Widgets
summary
Explains concrete claims and shows tools: why widget → element → render object matters for performance, when to use local versus app state, and when setState actually updates the UI. Demonstrates custom reusable widgets with constructor parameters and real app screenshots and behaviors, and points to new pieces like Firebase in DartPad, reorderable listview grab handle, Google Mobile Ads and devtools. Gives lifecycle methods, surprising community numbers and release notes so viewers know what code to try and which features already work.
