fluentTextareaUnderlineKey top-level constant

Key const fluentTextareaUnderlineKey

Identifies the CustomPaint that draws a textarea's border, whose bottom side is the resting bottom rule. Its painter is a FluentInputBorderPainter.

Public so a test — or a caller wrapping buildFluentTextarea — can find the border without matching on colour.

Implementation

const Key fluentTextareaUnderlineKey = Key('fluent-textarea-underline');
