FlutterLogoDecoration class

An immutable description of how to paint Flutter's logo.

Inheritance

• Object
• Decoration

Constructors

FlutterLogoDecoration({Color lightColor = const Color(0xFF42A5F5), Color darkColor = const Color(0xFF0D47A1), Color textColor = const Color(0xFF616161), FlutterLogoStyle style = FlutterLogoStyle.markOnly, EdgeInsets margin = EdgeInsets.zero})

Creates a decoration that knows how to paint Flutter's logo.

const

Properties

darkColor → Color?

The darker of the two colors used to paint the logo.

final

hashCode → int

The hash code for this object.

no setter, override

isComplex → bool

Whether this decoration is complex enough to benefit from caching its painting.

no setter, override

lightColor → Color?

The lighter of the two colors used to paint the logo.

final

margin → EdgeInsets?

How far to inset the logo from the edge of the container.

final

padding → EdgeInsetsGeometry

Returns the insets to apply when using this decoration on a box that has contents, so that the contents do not overlap the edges of the decoration. For example, if the decoration draws a frame around its edge, the padding would return the distance by which to inset the children so as to not overlap the frame.

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

style → FlutterLogoStyle

Whether and where to draw the "Flutter" text. By default, only the logo itself is drawn.

final

textColor → Color?

The color used to paint the "Flutter" text on the logo, if style is FlutterLogoStyle.horizontal or FlutterLogoStyle.stacked. The appropriate color is const Color(0xFF616161) (a medium gray), against a white background.

final

Methods

createBoxPainter([VoidCallback? onChanged]) → BoxPainter

Returns a BoxPainter that will paint this decoration.

override

debugAssertIsValid() → bool

In debug mode, throws an exception if the object is not in a valid configuration. Otherwise, returns true.

override

debugFillProperties(DiagnosticPropertiesBuilder properties) → void

Add additional properties associated with the node.

override

getClipPath(Rect rect, TextDirection textDirection) → Path

Returns a closed Path that describes the outer edge of this decoration.

inherited

hitTest(Size size, Offset position, {TextDirection? textDirection}) → bool

Tests whether the given point, on a rectangle of a given size, would be considered to hit the decoration or not. For example, if the decoration only draws a circle, this function might return true if the point was inside the circle and false otherwise.

override

lerpFrom(Decoration? a, double t) → FlutterLogoDecoration?

Linearly interpolates from another Decoration (which may be of a different class) to this.

override

lerpTo(Decoration? b, double t) → FlutterLogoDecoration?

Linearly interpolates from this to another Decoration (which may be of a different class).

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toDiagnosticsNode({String? name, DiagnosticsTreeStyle? style}) → DiagnosticsNode

Returns a debug representation of the object that is used by debugging tools and by DiagnosticsNode.toStringDeep.

inherited

toString({DiagnosticLevel minLevel = DiagnosticLevel.info}) → String

A string representation of this object.

inherited

toStringShort() → String

A brief description of this object, usually just the runtimeType and the hashCode.

inherited

Operators

operator ==(dynamic other) → bool

The equality operator.

override

Static Methods

lerp(FlutterLogoDecoration? a, FlutterLogoDecoration? b, double t) → FlutterLogoDecoration?

Linearly interpolate between two Flutter logo descriptions.
