AppDimens — Smart Responsive Dimensioning

Part of the AppDimens Flutter family — Flutter port of AppDimens Dynamic / AppDimens KMP.

The principal artifact: core engine, immutable window snapshots, snapshot-partitioned cache and the default Scaled strategy (sdp/hdp/wdp + text ssp/hsp/wsp, no-font-scale sem/hem/wem). 16.sdp resolves through a fast lane: one static snapshot read + one multiply.

Installation

dependencies:
  appdimens_flutter: ^3.2.0

Prefer one dependency for everything? Use appdimens_bom.

Usage

import 'package:appdimens_flutter/appdimens_flutter.dart';
final pad  = 16.sdp;    // smallest-width curve
final h    = 48.hdp;    // height curve
final size = 100.wdp;   // width curve

// conditional chain (priority: ui+qualifier → ui → qualifier → orientation)
final box = 100.scaledDp
    .screenMode(UiModeType.television, 500)
    .screenQualifier(DpQualifier.smallWidth, 600, 150);

Family grammar

Every strategy shares the same API grammar — suffixes (a · i · ia), orientation inverters (Ph/Lh/Pw/Lw), facilitators (Rotate/Mode/Qualifier/ Screen + Plain pairs), sp twins (ssp) and no-font-scale stems (sem):
