Craig Labenz compares breaking up large build methods using helper methods versus creating separate widget classes in Flutter.

Flutter developers are well-acquainted with widget build methods that grow, and grow… and grow. In this video, Craig Labenz compares two different ways to break up those unwieldy build methods; and how the best option may be different than what you originally suspected. See the differences in action in these DartPads: Managing rebuilds with nested const widgets → goo.gle/3yallg1 Managing rebuilds with nested non-const widgets → goo.gle/3IyafpM Preventing errors with separate widgets → goo.gle/3dDrR5o Helper methods can create a requirement for Keys → goo.gle/31HlnQB Get started with Flutter → goo.gle/Flutter Learn more about the Dart Language → goo.gle/2YF9OCi Watch more Decoding Flutter episodes → goo.gle/DecodingFlutter Don’t miss an episode, subscribe to Flutter → goo.gle/FlutterYT #DecodingFlutter #Flutter #Developer product: Flutter - Development - User interface;

Hi, I’ve noticed that many of Flutter’s built-in widgets use helper methods to return widgets. Here are a few examples (there are many more): * **Slider (decorator):** https://github.com/flutter/flutter/blob/main/packages/flutter/lib/src/material/slider.dart#L801 * **InputDecorator:** https://github.com/flutter/flutter/blob/70a3c3cc935e49b44db818348dd2d57f055ab762/packages/flutter/lib/src/material/input\_decorator.dart#L401 * **Stepper:** https://github.com/flutter/flutter/blob/70a3c3cc935e49b44db818348dd2d57f055ab762/pac…
