TooltipBubble class
Small candy-styled speech-bubble container for coach-mark/hint use cases.
A rounded rect body + a triangular pointer nub on one edge, drawn as a
single Path via CustomPainter (fill + stroke) so the nub reads as
part of the same shape rather than a separately-clipped overlay. Wraps
arbitrary child content — pass a Text directly for a plain label, or
use TooltipBubble.text as a shortcut for that common case.

Constructors
- TooltipBubble({Key? key, required Widget child, Color? color, TooltipPointerDirection direction = TooltipPointerDirection.up, double nubAlign = 0.5, EdgeInsetsGeometry padding = const EdgeInsets.symmetric(horizontal: NeonTheme.s16, vertical: NeonTheme.s8)})
-
const
- TooltipBubble.text(String text, {Key? key, Color? color, TooltipPointerDirection direction = TooltipPointerDirection.up, double nubAlign = 0.5, EdgeInsetsGeometry padding = const EdgeInsets.symmetric(horizontal: NeonTheme.s16, vertical: NeonTheme.s8)})
- Convenience for the plain-text-label case.
Properties
- child → Widget
-
final
- color → Color?
-
Defaults to NeonTheme.purple — nullable because a
NeonThemecolor field is no longer a compile-time constant.final - direction → TooltipPointerDirection
-
final
- hashCode → int
-
The hash code for this object.
no setterinherited
- key → Key?
-
Controls how one widget replaces another widget in the tree.
finalinherited
- nubAlign → double
-
Horizontal position of the nub, 0 (reading-start) .. 1 (reading-end)
of the bubble width — physical left..right in LTR, physical
right..left in RTL (ENH-38), so a caller says "near the start of the
thing it's pointing at" without caring which locale is active.
Clamped away from the rounded corners inside the painter.
final

final
- runtimeType → Type
-
A representation of the runtime type of the object.
