ViewportConfiguration class

A configuration for the viewport.

Constructors

ViewportConfiguration({bool overshootEffect = false, bool extendPage = false, double minFraction = 0.9, double maxFraction = 1.0, ViewportInset shrunkInset = ViewportInset.shrunk, ViewportInset? initialInset, List<ViewportInset> extraSnapInsets = const []})

Create a configuration for standard use cases.

factory

ViewportConfiguration.raw({bool extendPage = false, double minFraction = 0.9, double maxFraction = 1.0, ViewportInset minInset = ViewportInset.expanded, ViewportInset maxInset = ViewportInset.shrunk, ViewportInset shrunkInset = ViewportInset.shrunk, ViewportInset expandedInset = ViewportInset.expanded, ViewportInset initialInset = ViewportInset.shrunk, List<ViewportInset> snapInsets = const [ViewportInset.expanded, ViewportInset.shrunk]})

A general constructor for ViewportConfiguration.

const

Properties

expandedInset → ViewportInset

final

extendPage → bool

If true, the page extends to the bottom of the viewport when it fully expanded, even if the viewport has non-zero bottom padding.

final

hashCode → int

The hash code for this object.

no setter, override

initialInset → ViewportInset

The initial viewport inset.

final

maxFraction → double

The upper bound of fraction.

final

maxInset → ViewportInset

The upper bound of the inset.

final

minFraction → double

The lower bound of fraction.

final

minInset → ViewportInset

The lower bound of the inset.

final

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

shrunkInset → ViewportInset

The lower bound of the inset at which the current page viewport is fully shrunk.

final

snapInsets → List<ViewportInset>

The list of insets that the viewport will snap to.

final
