text property

TextSpan text

The (potentially styled) text to paint.

After this is set, you must call layout before the next call to paint.

This and textDirection must be non-null before you call layout.

Implementation 

TextSpan get text => _text;
void text= (TextSpan value)

Implementation 

set text(TextSpan value) {
  assert(value == null || value.debugAssertIsValid());
  if (_text == value)
    return;
  if (_text?.style != value?.style)
    _layoutTemplate = null;
  _text = value;
  _paragraph = null;
  _needsLayout = true;
}
