fix: resolve non-constant IconData preventing icon font tree-shaking by ps9310 · Pull Request #427 · ZebraDevs/zeta_flutter

ps9310 · 2026-03-27T11:00:43Z

Summary

Replace _copyWith() in IconExtensions.apply() with a lookup into const iconsRound/iconsSharp maps, eliminating non-constant IconData construction that broke --tree-shake-icons
Add iconsRound and iconsSharp codePoint lookup maps to zeta_icons (will be auto-generated by the zeta-icons template going forward)
Replace non-constant IconData in example app with ZetaIcon widget
Bump zeta_icons 1.9.2 → 1.9.3, zeta_flutter 1.4.4 → 1.4.5

Fixes the Flutter web release build error:

This application cannot tree shake icons fonts. It has non-constant instances of IconData

Depends on

fix: generate iconsRound and iconsSharp lookup maps in icons.g.dart zeta-icons#150

Test plan

All 12 icon tests pass
flutter build web --release --tree-shake-icons succeeds
Icon fonts are tree-shaken (MaterialIcons 99.4%, zeta-icons-sharp 18.7%, zeta-icons-round 14.9%)
flutter analyze passes with no issues
