buildTextSpan method

@override TextSpan buildTextSpan({required BuildContext context, TextStyle? style, required bool withComposing})

Builds TextSpan from current editing value.

By default makes text in composing range appear as underlined. Descendants can override this method to customize appearance of text.

Implementation

@override
TextSpan buildTextSpan({
  required BuildContext context,
  TextStyle? style,
  required bool withComposing,
}) {
  if (_parser == null) {
    _init();
  }

  return _textSpanNotifier.elements.isEmpty
      ? TextSpan(
          text: _textSpanNotifier.value.text,
          style: style,
        )
      : TextSpan(
          children: _textSpanNotifier.value.children,
          // The style from buildTextSpan() must be applied to the
          // top level. Applying it to the children instead causes
          // the following behaviours.
          //
          // * The height is not applied to the cursor.
          // * Changes in the style specified in editable text are
          //   not reflected quickly.
          style: style,
        );
