Power

Strategy module: appdimens_power · part of the AppDimens Flutter family

What it is

Raises the normalized axis to a fixed exponent (0.75), producing growth slower than linear — sizes increase on tablets, but less and less.

Calculation used

out = b × (d × ι)^0.75

The default path reuses the snapshot-memoized powerScale factor (one multiply, no pow per call).

How to use

import 'package:appdimens_power/appdimens_power.dart';
final pad = 16.pwsdp;      // sub-linear on sw
final h   = 16.pwhdp;
final w   = 16.pwwdp;
final ar  = 16.pwsdpa;     // + aspect-ratio multiplier

Why use it

Pure linear scaling makes phone UIs feel sparse on tablets; a 0.75 exponent keeps proportions pleasant without a breakpoint system.

When to use it

Spacing, icon sizes and components that should grow moderately on large screens.

Advantages & trade-offs

✅ Advantages	⚠️ Trade-offs
Smooth, monotonic, no breakpoints · memoized fast path · AR multiplier optional
---	---

Recommended usage strategy

Choose Power when Scaled feels too aggressive on tablets but Auto/Logarithmic feel too conservative.
