buildTextSpan method

@override TextSpan buildTextSpan()

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() {
  final detections = detector.getDetections(textEditingValue.text);
  final composer = Composer(
    selection: textEditingValue.selection.start,
    onDetectionTyped: widget.onDetectionTyped,
    sourceText: textEditingValue.text,
    decoratedStyle: widget.decoratedStyle,
    detections: detections,
    composing: textEditingValue.composing,
  );
  if (detections.isEmpty) {
    /// use same method as default textField to show composing underline
    return widget.controller.buildTextSpan(
      context: context,
      style: widget.style,
      withComposing: !widget.readOnly,
    );
  }
  return composer.getComposedTextSpan();
}
