Methods

buildWidget(CanvasNode node, BuildContext context, WidgetBuildSettings settings) → Widget

Transforms a node into some output.

override

canvasBackground(BuildContext context, CanvasNode node) → Color?

The canvas's background: its fill, except for a dialog's canvas that fills the screen because it holds a responsive layout; its layout draws the dialog, and its fill would hide the screen behind the barrier.

followsScreen(CanvasNode node) → bool

Whether node fills the space it is shown in even as a dialog: a responsive canvas holding a responsive layout, whose layout draws the dialog. A canvas that hugs its content is a card of its own size instead (a confirm dialog), centered like any dialog; its layout still picks the variant for the screen's width.

getAppBar(BuildContext context, CanvasNode node, WidgetBuildSettings settings) → PreferredSizeWidget?

getFAB(BuildContext context, CanvasNode node, WidgetBuildSettings settings) → Widget?

getNavigationBar(BuildContext context, CanvasNode node, WidgetBuildSettings settings) → Widget?

hasNearbyResponsiveLayout(CanvasNode node) → bool

This would not work if the canvas is expected to have 2 different forms. For that to work, a custom Form node is required. However, that's rarely the case most of the time, so this should work for most cases! Whether node's layout is responsive: a variance with breakpoints within its body's first levels, where layouts.createResponsive puts one.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

onFaBPressed(BuildContext context, CanvasNode node) → void

showsOverScreen(CanvasSizing sizing, CanvasNode node) → bool

Whether node, shown with sizing, fills the screen as a dialog.

toString() → String

A string representation of this object.

inherited

wrapWithSafeArea(SafeAreaModel safeArea, Widget body) → Widget

Operators

operator ==(Object other) → bool

The equality operator.

Static Methods

getBodyChildren(CanvasNode node) → List<String>

hasResponsiveLayout(BaseNode node, GetNode getNode) → bool

Whether node or a node under it is a responsive layout (a VarianceNode whose variants map to breakpoints), in any variant.

retrieveBackgroundColor(BuildContext context, CanvasNode node) → Color?

Constants

name → const String
