Whether a TextPosition is visually upstream or downstream of its offset.
For example, when a text position exists at a line break, a single offset has two visual positions, one prior to the line break (at the end of the first line) and one after the line break (at the start of the second line). A text affinity disambiguates between those cases. (Something similar happens with between runs of bidirectional text.)
Constants
- downstream → TextAffinity
-
The position has affinity for the downstream side of the text position.
For example, if the offset of the text position is a line break, the position represents the start of the second line.
const TextAffinity(1) - upstream → TextAffinity
-
The position has affinity for the upstream side of the text position.
For example, if the offset of the text position is a line break, the position represents the end of the first line.
const TextAffinity(0) - values → List<TextAffinity>
-
A constant List of the values in this enum, in order of their declaration.
const List<TextAffinity>
