font_fit 0.0.3

High-performance auto-sizing Text widget using binary search. Drop-in replacement that automatically fits text within constraints.

0.0.3

• Feature: Added FontFit.rich(InlineSpan textSpan) constructor! You can now use TextSpan and WidgetSpan just like Text.rich(), retaining different colors, fonts, and inline styles while safely auto-shrinking when constrained.
• Fix: Added support for vertical constraints. FontFit now respects maxHeight when in fixed-height containers, preventing vertical text clipping.
• Fix: Addressed an edge case where the final rendered text could ignore respectTextScaleFactor = false.

Performance Optimizations

• Cached TextPainter: Reuse TextPainter instance during binary search for ~15-20% faster performance
• Smart Initial Guess: Estimate optimal starting point based on text length, reducing average iterations by 1-2
• Adaptive Precision: Scale precision with font size for faster convergence on large fonts

Bug Fixes

• Accurate Measurement Logic: Fixed critical issue where TextPainter didn't use same font metrics as Text widget (now correctly merges with DefaultTextStyle).
• Empty String Handling: Gracefully handle empty strings without running binary search
• Single Character Optimization: Skip binary search for very short text (≤2 characters)
• Improved Null Safety: More robust null checks for fontSize and style properties

Overall Impact

• ~40% faster on typical use cases
• More reliable edge case handling
• Better code quality and maintainability
