Layer class - layer library

Constructors

Layer({GlobalKey<State<StatefulWidget>>? key, String? id, LayerInteraction? interaction, Offset offset = Offset.zero, double rotation = 0, double scale = 1, bool flipX = false, bool flipY = false, Map<String, dynamic>? meta, BoxConstraints? boxConstraints, String? groupId}): Creates a new layer with optional properties.
Layer.fromMap(Map<String, dynamic> map, {List<Uint8List>? widgetRecords, WidgetLoader? widgetLoader, String? id, dynamic requirePrecache(EditorImage editorImage)?, EditorKeyMinifier? minifier}): Factory constructor for creating a Layer instance from a map and a list of stickers.

Methods

computeLocalCenterOffset(Offset fractionalOffset) → Offset: Computes the local offset within the render box using a fractional position relative to the center of the box (excluding the global offset).
computeOffsetFromCenterFraction(Offset fractionalOffset) → Offset: Computes the global offset within the render box using a fractional position relative to the center of the box.
copyWith({String? id, String? groupId, Offset? offset, double? rotation, double? scale, bool? flipX, bool? flipY, LayerInteraction? interaction, Map<String, dynamic>? meta, BoxConstraints? boxConstraints}) → Layer: Creates a copy of this Layer with the given fields replaced with new values.
debugFillProperties(DiagnosticPropertiesBuilder properties) → void: Fills the given DiagnosticPropertiesBuilder with properties of this layer for debugging and development tools.
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
toMap({int maxDecimalPlaces = kMaxSafeDecimalPlaces, bool enableMinify = false}) → Map<String, dynamic>: Converts this transform object to a Map.
toMapFromReference(Layer layer, {int maxDecimalPlaces = kMaxSafeDecimalPlaces, bool enableMinify = false}) → Map<String, dynamic>: Converts the current layer to a map representation, comparing it with a reference layer.
toString() → String: A string representation of this object.
inherited

Operators

operator ==(Object other) → bool: The equality operator.
