import {
  type TreeNode,
  type TreeViewRef
} from 'react-native-tree-multi-select';

// Refer to the Properties table below or the example app for the TreeNode type
const myData: TreeNode[] = [...];

export function TreeViewUsageExample(){
  const treeViewRef = React.useRef<TreeViewRef | null>(null);
  // It's recommended to use debounce for the search function (refer to the example app)
  function triggerSearch(text: string){
    // Pass search text to the tree along with the keys on which search is to be done(optional)
    treeViewRef.current?.setSearchText(text, ["name"]);
  // Callback functions for check and expand state changes:
  const handleSelectionChange = (checkedIds: string[]) => {
    // NOTE: Do something with updated checkedIds here
  const handleExpanded = (expandedIds: string[]) => {
    // NOTE: Do something with updated expandedIds here

  // Expand collapse calls using ref
  const expandAllPress = () => treeViewRef.current?.expandAll?.();
  const collapseAllPress = () => treeViewRef.current?.collapseAll?.();

  // Multi-selection function calls using ref
  const onSelectAllPress = () => treeViewRef.current?.selectAll?.();
  const onUnselectAllPress = () => treeViewRef.current?.unselectAll?.();
  const onSelectAllFilteredPress = () => treeViewRef.current?.selectAllFiltered?.();
  const onUnselectAllFilteredPress = () => treeViewRef.current?.unselectAllFiltered?.();
    // ... Remember to keep a fixed height for the parent. Read Flash List docs to know why
