GlassDefaults class

Default values for glass visual properties.

Properties

hashCode → int

The hash code for this object.

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

Methods

noSuchMethod(Invocation invocation) → dynamic

inherited

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool

The equality operator.

Static Methods

safeBorderRadius(double radius) → BorderRadius

Converts a radius to a BorderRadius.circular with safe finite bounds.

safeCircularRadius(double radius) → Radius

Converts a radius to a Radius.circular with safe finite bounds.

safeRadius(double radius) → double

Clamps or replaces non-finite radii (such as double.infinity) with maxSafeRadius, while ensuring the radius is at least 0.0.

safeVerticalBorderRadius(double top, double bottom) → BorderRadius

Converts top and bottom radii to a vertical BorderRadius with safe finite bounds.

Constants

ambientBaseLight → const double

Even surface brightening of a pressed button in light mode — measured at about +15 luma against a native iOS 26 press (0.3)

ambientBaseLightDark → const double

Dark-mode counterpart: the darker resting surface needs half the overlay for the same read. Estimated pending a native dark-mode capture (0.14)

ambientLiftDuration → const Duration

The pressed lift ramps over the press inflation (150 ms)

ambientLiftReverseDuration → const Duration

...and collapses on release (60 ms)

animationDuration → const Duration

Standard animation duration for glass effects (200ms)

animationDurationFast → const Duration

Fast animation duration for quick transitions (100ms)

animationDurationSlow → const Duration

Slow animation duration for deliberate effects (300ms)

barrierColor → const Color

Barrier colour for modal overlays (sheets, action sheets). iOS 26 uses 54% black to dim content behind modals.

blur → const double

Default blur amount for glass effects (3.0)

borderRadius → const double

Standard border radius for most glass widgets (16.0)

borderRadiusLarge → const double

Large border radius for prominent elements (20.0)

borderRadiusSmall → const double

Small border radius for compact elements (8.0)

capsuleRadius → const double

Sentinel radius that produces a perfect capsule (stadium) shape at any widget height.

chromaticAberration → const double

Default chromatic aberration amount (0.5)

dematerializeDuration → const Duration

Exit duration of the materialize glass transition (350ms).

heightButton → const double

Standard height for buttons (48.0)

heightControl → const double

Standard height for interactive controls (32.0)

heightInput → const double

Standard height for input fields (48.0)

lightAngle → const double

Default light angle in radians (135° = 0.75 * π — Apple iOS 26 standard, upper-left light)

lightIntensity → const double

Default light intensity for specular highlights (2.0)

materializeDuration → const Duration

Entrance duration of the materialize glass transition (250ms).

maxSafeRadius → const double

Maximum safe finite corner radius used to guard against double.infinity collapsing to 0.0 in Flutter's RRect scaling algorithm.

paddingCard → const EdgeInsets

Standard padding for card-like widgets

paddingCompact → const EdgeInsets

Compact padding for small elements

paddingInput → const EdgeInsets

Standard padding for input fields

paddingMinimal → const EdgeInsets

Minimal padding for tight layouts

paddingPanel → const EdgeInsets

Standard padding for panel-like widgets

refractiveIndex → const double

Default refractive index for glass (1.15)

specularDarkAlpha → const double

Specular tint applied to drag handles and pill surfaces (dark mode).

specularLightAlpha → const double

Specular tint applied to drag handles and pill surfaces (light mode).

thickness → const double

Default glass thickness for most widgets (30.0)
