Hello.
Can you help me?
I am trying to implement the onDidChangeTreeData on the dataProvider in an UncontrolledTreeEnvironment but I dont know how and I dont see any examples of it. I want the tree data to refresh when I click on a element of the tree.

dataProvider={{
onDidChangeTreeData: // ? what do I do ?
getTreeItem: async (itemId) => {
return new Promise((res) => res(listItems[itemId]));
},
}}

Hi @jorgeanjos! There are essentially two ways how tree data can be changed, either by moving items to a different location (which will invoke dataProvider.onChangeItemChildren()) or by renaming an item (which will invoke dataProvider.onRenameItem()). Please use these methods to get informed of data changes. The onDidChangeTreeData prop is a event emitter that the data provider can optionally implement to propagate change events to outside, which mostly is used by the StaticTreeDataProvider to allow external consumers to register change events. I admit that the naming here is suboptimal, as onDidChangeTreeData is not an event itself but an emitter, maybe that should be renamed..
