HintArrowGeometry class Theming

Where the caret sits and which way it points, handed to a HintArrowBuilder.

Everything is already resolved for the side the bubble landed on, so a custom caret is written once and works on all four edges: build it from baseCentre, along and tip rather than from raw x/y.

Creates the geometry handed to a custom arrow builder.

const

Properties

along → Offset

A unit vector along that edge.

final

baseCentre → Offset

The midpoint of the caret's base, on the bubble's edge.

final

baseEnd → Offset

The base corner on the along-positive side.

no setter

baseStart → Offset

The base corner on the along-negative side.

no setter

halfWidth → double

Half the caret's width along the edge.

final

hashCode → int

no setter, override

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

side → HintSide

The side of the target the bubble sits on.

final

size → Size

The caret's box: width along the edge, height away from it.

final

tip → Offset
