GlassContainer class

A widget that combines common painting, sizing and positioning widgets to implement Glass Morphism.

A GlassContainer surrounds the child in a Container with necessary decoration properties like color, gradient, borderRadius and shape. Preference is given to gradient and borderGradient during painting.

GlassContainer paints border using CustomPaint with RectBorderPainter or CircleBorderPainter depending on the box shape.

BackdropFilter, frosted layer and container are stacked and clipped using ClipOval or ClipRRect to implement the Glass Effect

Properties

alignment → AlignmentGeometry?
Align the child within the GlassContainer.
final
blur → double
The value of sigmaX and sigmaY properties of Gaussian Blur. In simple words its the extent to which the backdrop of GlassContainer is blurred
final
borderColor → Color?
The color to fill in the border
final
borderGradient → Gradient?
A gradient to use when painting the border
final
borderRadius → BorderRadius?
If non-null, the corners of this box are rounded by this BorderRadius.
final
borderWidth → double
The strokeWidth of the border
final
boxShadow → List<BoxShadow>?
A list of shadows cast by this container behind it.
final
child → Widget?
The child contained by the GlassContainer.
final
color → Color?
The color to fill in the background of the box.
final
frostedOpacity → double
Opacity value of the frosted layer. Specifically its the opacity of the white-noise image used for the effect.
final
gradient → Gradient?
A gradient to use when filling the box.
final
hashCode → int
The hash code for this object.
no setterinherited
height → double?
The height of the GlassContainer
final
isFrostedGlass → bool
Whether the GlassContainer will have frosted effect or not.
final
key → Key?
Controls how one widget replaces another widget in the tree.
finalinherited
margin → EdgeInsetsGeometry?
Empty space to surround the GlassContainer's decoration and child.
final
padding → EdgeInsetsGeometry?
Empty space to inscribe inside the GlassContainer. The child, if any, is placed inside this padding.
final
runtimeType → Type

no setterinherited
shape → BoxShape
The shape to fill the background color, gradient into and to cast as the shadow. The heigth is used as the diameter of the circle
final
transform → Matrix4?
The transformation matrix to apply before painting the GlassContainer.
final
transformAlignment → AlignmentGeometry?
The alignment of the origin, relative to the size of the GlassContainer, if transform is specified.
final
width → double?
