GutterTheme constructor

const GutterTheme({
  1. double gutterCalc(
    1. double screenWidth
    ) = _defaultGutterCalc,
  2. bool enabled = true,
})

Creates a GutterTheme with the specified configuration.

Initializes the theme for use in ArcaneTheme, applying to all gutter-related widgets. The gutterCalc parameter accepts a function that computes padding from screen width, defaulting to a responsive formula that grows from 25px on small screens to up to 1/3 screen width on large ones, ensuring adaptive layouts. The enabled parameter sets default activation, allowing theme-wide disabling for edge-to-edge designs while permitting per-widget overrides.

This constructor supports const creation for performance in theme definitions, integrating with ArcaneTheme.of(context).gutter for runtime access.

Implementation

const GutterTheme(
    {this.gutterCalc = _defaultGutterCalc, this.enabled = true});
