/**
 * Creates a flag-shaped bullet with an optional text label inside it.
 *
 * The background/body of the flag is a [[WavedRectangle]] element. Most of
 * its the visual appearance is configured via `background` property.
 *
 * The size of a background adopts to the size of a label automatically. If
 * you don't want a label to be shown at all, you can set it to `undefined`. In
 * this case flag size will be of the `width`/`height` set directly on the
 * [[FlagBullet]].
 *
 * Uses [[Label]] instance to draw the label, so the label itself is
 * configurable.
 *
 * Example:
 *
 * ```TypeScript
 * let series = chart.series.push(new am4charts.LineSeries());
 * // ...
 * let flagBullet = series.bullets.push(new am4plugins_bullets.FlagBullet());
 * flagBullet.poleHeight = 15;
 * flagBullet.label.text = "{valueY}";
 * ```
 * ```JavaScript
 * var series = chart.series.push(new am4charts.LineSeries());
 * // ...
 * var flagBullet = series.bullets.push(new am4plugins_bullets.FlagBullet());
 * flagBullet.poleHeight = 15;
 * flagBullet.label.text = "{valueY}";
 * ```
 * ```JSON
 * {
 *   // ...
 *   "series": [{
 *     // ...
 *     "bullets": [{
 *       "type": "FlagBullet",
 *       "poleHeight": 15,
 *       "label": {
 *         "text": "{valueY}"
 *       }
 *     }]
 *   }]
 * }
 * ```
 *
 * @since 4.5.7
 * @see {@link https://www.amcharts.com/docs/v4/tutorials/plugin-bullets/} for usage instructions.
