flutter_tailwind 2.0.1

I hope to make something like tailwind that can simplify the description of style and improve efficiency.

2.0.1

Fixes

• Fix AutoSizeText assertion crash when using .text.fN.fM.mk (auto-shrink-to-fit text) together with a non-Identity SizeAdapter. v2.0.0's ssp() threading produced fractional values that violated AutoSizeText's stepGranularity=1 requirement. Both minFontSize and the style's fontSize are now rounded to integers after ssp(). Regression test added covering a _MockFractionalSpAdapter (mimics screenutil-on-desktop .sp factors).

2.0.0

Breaking changes

• Removed adaptW / adaptH / adaptR / adaptSp getters. Replaced by global configuration via Tailwind.instance.configSizeAdapter(...). To preserve the old behavior, write a 4-line SizeAdapter that wraps screenutil — see doc/patterns/screen-adaptation.md.
• Removed flutter_screenutil dependency. The library no longer transitively pulls screenutil. If your project relied on the indirect export (e.g. ScreenUtilInit imported via package:flutter_tailwind), add flutter_screenutil to your own pubspec.yaml.
• Removed Tailwind.instance.context field. init() now extracts needed values from the context immediately and does not retain it. .primary no longer needs a try-catch (the deactivated-context throw scenario cannot happen anymore).
• p16 / p20 are now top-level getters (were final variables). Calling syntax (padding: p16) unchanged but each access now routes through SizeAdapter.

New

• SizeAdapter abstract class — 4-method interface (w/h/r/sp) that decouples the library from any specific screen-adaptation package. Default IdentitySizeAdapter (no scaling).
• Tailwind.instance.screenW / screenH — cached screen dimensions populated by init(context). Used internally by the hFull/wFull family; also exposed for user code.
• Tailwind.instance.configSizeAdapter(adapter) — install your scaling implementation, typically once at app startup.

Migration (1.x → 2.0)

1. Remove every .adaptW/.adaptH/.adaptR/.adaptSp call from your code.
2. If you used screen scaling, write a SizeAdapter subclass:

   class ScreenUtilSizeAdapter implements SizeAdapter {
     const ScreenUtilSizeAdapter();
     @override double w(double v) => v.w;
     @override double h(double v) => v.h;
     @override double r(double v) => v.r;
     @override double sp(double v) => v.sp;
   }
   void main() {
     Tailwind.instance.configSizeAdapter(const ScreenUtilSizeAdapter());
     runApp(...);
   }
   

3. If you used hFull/wFull-family getters, call Tailwind.instance.init(context) from inside MaterialApp.builder (or any context inside MaterialApp).

1.8.0

• Tailwind.instance.primary no longer throws Looking up a deactivated widget's ancestor is unsafe when accessed after the holding widget has been disposed; it now falls back to primaryColor ?? Colors.amber. Added 5 widget tests covering init/no-init/disposal scenarios — the first real unit tests in this repo.
• Replaced deprecated Color.withOpacity with Color.withValues(alpha:) internally (no behavior change for users — same alpha-modified color, better precision in the new color pipeline).
• New doc/ directory as the documentation single-source-of-truth:
  • doc/getting-started.md — install, bare-minimum usage, theme primary color setup with the correct init position
  • doc/patterns/screen-adaptation.md — .adaptW / .adaptH / .adaptR / .adaptSp (the opt-in screen-scaling API introduced in 1.7.x but undocumented until now)
  • doc/patterns/spacing.md — spacing2..spacing32 shortcuts vs manual spacers
• .cursor/rules/flutter_tailwind.mdc fixed several stale teachings:
  • Removed the recommendation to run flutter packages pub run build_runner build (this library does not use build_runner)
  • Rewrote the Tailwind.instance.init(context) example — init must be called from inside MaterialApp, not from ScreenUtilInit.builder (the context there is above MaterialApp, so Theme.of returns ThemeData.fallback() instead of your theme — .primary ends up the wrong color)
• README adds a documentation-navigation section at the top and an explicit note that this library does not use build_runner.
• guide.md adds a migration banner pointing at doc/.
