onInit method

@override void onInit()

Called immediately after the widget is allocated in memory. You might use this to initialize something for the controller.

Implementation

@override
void onInit() {
  super.onInit();

  initializeTabsJson();
  final tabData = tabsJson[screen];

  if (tabData != null && tabData.isNotEmpty) {
    headerHeight.value =
        tabData['section']['subHeader'] - tabData['section']['header'];

        tabData['section']['body'] - tabData['section']['subHeader'];
    bodyHeight.value =
        tabData['section']['subBody'] - tabData['section']['body'];
    subBodyHeight.value =
        tabData['section']['footer'] - tabData['section']['subBody'];
    footerHeight.value = 842.00 - tabData['section']['footer'];

    _updateSectionPositionsOnly();

    List<PrinterDesignerPackageListModel> restoredItems =
    convertJsonStringPositions(jsonEncode(tabData));
    items.value = restoredItems;
    tableVisibleHeaders.value = convertJsonStringTableHeaders() ?? [];
  } else {
