insertText method

int insertText(
  1. String value
)

Inserts the longest whole-grapheme prefix that fits maxLength. Returns the number of UTF-16 code units inserted.

Implementation

int insertText(String value) {
  final inserted = _truncate(
      value, maxLength == null ? value.length : maxLength! - length);
  if (inserted.isEmpty) return 0;
  final position = _cursorPosition + inserted.length;
  _replace('$textBeforeCursor$inserted$textAfterCursor', position,
      roundUp: true);
  return inserted.length;
}
