getTextBoundaryAt method

TextRange getTextBoundaryAt(
  1. int position
)

Returns the text boundary range that encloses the input position.

The returned TextRange may contain -1, which indicates no boundaries can be found in that direction.

Implementation

TextRange getTextBoundaryAt(int position) {
  final int start = getLeadingTextBoundaryAt(position) ?? -1;
  final int end = getTrailingTextBoundaryAt(position) ?? -1;
  return TextRange(start: start, end: end);
}
