Filter class

🔬 Filter

A 🌟 Surface may be provided a 🔬 Filter to alter filter appearance at all 📚 SurfaceLayers.

Constructors

Filter({Set<SurfaceLayer> filteredLayers = BASE, Map<SurfaceLayer, double>? radiusMap, double? baseRadius, double? materialRadius, double? childRadius, bool extendBaseFilter = false, SurfaceFX effect = FX.blurry})

🔬 Filter

const

Properties

baseRadius → double?

Instead of initializing a 📊 radiusMap, opt to pass a specific layer's 🤹‍♂️ effect radius with this property.

final

childRadius → double?

Instead of initializing a 📊 radiusMap, opt to pass a specific layer's 🤹‍♂️ effect radius with this property.

final

effect → SurfaceFX

🤹‍♂️ Surface FX

final

extendBaseFilter → bool

If extendBaseFilter is true, the BackdropFilter for 📚 SurfaceLayer.BASE will extend to cover the Surface.margin padding.

final

filteredLayers → Set<SurfaceLayer>

Provide a Set{} to 👓 filteredLayers to specify which 📚 SurfaceLayers will have an effect 🤹‍♂️ SurfaceFX enabled.

final

hashCode → int

The hash code for this object.

no setter, inherited

literalRadiusBase → double

no setter

literalRadiusChild → double

no setter

literalRadiusMaterial → double

no setter

materialRadius → double?

Instead of initializing a 📊 radiusMap, opt to pass a specific layer's 🤹‍♂️ effect radius with this property.

final

radiusMap → Map<SurfaceLayer, double>?

📊 radiusMap Maps one or more 📚 SurfaceLayers to a double that determines the 🤹‍♂️ SurfaceFX radius for that layer's 🤹‍♂️ effect.

final

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

Methods

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

radiusByLayer(SurfaceLayer layer) → double

Check if � radiusMap has a value for this 📚 layer and return if so; if not, then check if this 📚 layer was initialized a specific double (such as � baseRadius) and return if so; finally, if all else fails, return const _BLUR

toString() → String

A string representation of this object.

inherited

Operators

operator ==(Object other) → bool

The equality operator.

Constants

BASE → const Set<SurfaceLayer>

👓 Base

BASE_AND_CHILD → const Set<SurfaceLayer>

👓 Base & Child

BASE_AND_MATERIAL → const Set<SurfaceLayer>

👓 Base & Material

CHILD → const Set<SurfaceLayer>

👓 Child

DEFAULT → const Filter

A new 🌟 Surface defaults 🔬 Surface.filter to this DEFAULT, which differs from a (new) FilterSpec.

INNER_BILAYER → const Set<SurfaceLayer>

👓 Inner Bilayer

MATERIAL → const Set<SurfaceLayer>

👓 Material

NONE → const Set<SurfaceLayer>

👓 None

TRILAYER → const Set<SurfaceLayer>

👓 Trilayer
