sizing 2.0.1

Flutter package for scaling UI elements proportionally across screen sizes. One extension for fonts, containers, padding, and radius — design proportions always preserved.

2.0.1

• Fix README demo image not rendering on pub.dev (use absolute GitHub raw URL).

2.0.0

Breaking change — complete redesign. See migration notes below.

New features

• New scaling algorithm: compares short-side to short-side and long-side to long-side, making calculations orientation-agnostic. Rotating the device no longer breaks the layout.
• baseSize can be passed in any orientation — Size(390, 850) and Size(850, 390) produce identical results.
• Three scaling models:
  • .s — Power (default): size × ratio^factor. Grows fast for small ratios and flattens naturally on large screens (tablets).
  • .l — Linear: size × (1 + (ratio − 1) × factor). Constant growth, useful for hero images and illustrations.
  • .c — Custom: developer-defined CustomScaleFunction.
• .f(double newFactor) — inline factor override for a single element, without touching global state.
• .w / .h — screen width and height percentages (replaces .sw / .sh).
• SizingBuilder now accepts respectSystemFontScale, scaleLayoutWithFont, factor, and customScale.
• Full control of textScaler via MediaQuery override: the package takes responsibility for accessibility scaling, eliminating the double-scaling bug present in v1.
• Dart SDK updated to >=3.0.0.

Removed (breaking)

v1	v2 replacement
.ss	.s
.fs	.s
.fss	.s
.vs	.s (short/long ratio approach replaces axis distinction)
.sw	.w
.sh	.h
.self(bool)	respectSystemFontScale on SizingBuilder
differentFactor()	.s.f(newFactor)
selfFontScale()	removed
systemFontScale (builder param)	respectSystemFontScale

Migration quick-reference

// Before
SizingBuilder(systemFontScale: true, builder: () => ...)
16.fss   →  16.s
100.ss   →  100.s
100.vs   →  100.s
0.5.sw   →  0.5.w
0.5.sh   →  0.5.h
16.fss.f(0.8)  →  16.s.f(0.8)
