updateHeading method

void updateHeading(
  1. String newHeading
)

Updates the heading text and re-renders.

Has no effect once the section isFinished; the completion message (successMessage or failedMessage) still takes precedence at that point, exactly as it did with the heading set at construction time.

Implementation

void updateHeading(final String newHeading) {
  if (_finished) return;
  _heading = newHeading;
  _render();
}
