react-native - wix react-native-navigation 版本 2 - Fab 图标未显示在屏幕上

Question

Fab 图标不显示在屏幕上。我已经根据 V2 文档添加了源代码，如下所示。

  static get options() {
    return {
      topBar: {
        title: {
          text: "Collapse",
          color: "black",
          fontSize: 16
        },
        drawBehind: true,
        visible: true,
        testID: "addLiveSale"
      },
      fab: {
        id: "addLiveSale",
        backgroundColor: "blue",
        clickColor: "blue",
        rippleColor: "aquamarine",
        hideOnScroll: true
      }
    };
  }
