Returns the latest position within this component's DocumentNode that appears at or near the given x position.
override
getOffsetForPosition(dynamic nodePosition) → Offset
Returns the (x,y) Offset for the given nodePosition, or throws an exception if the given nodePosition is not compatible with this component's node type.
override
getPositionAtEndOfLine(TextNodePosition textPosition) → TextNodePosition
Returns the TextNodePosition that corresponds to the last character in the line of text that contains the given textNodePosition.
override
getPositionAtOffset(Offset localOffset) → TextNodePosition?
