Generate TreeViewItems From data about fluent_ui HOT 3 CLOSED

Hello!

¹ Maybe Iterable.map method is the way to go? Something like the following:

final items = data.map<TreeViewItem>((e) {
  return TreeViewItem(
    ...,
  );
}).toList();

² You can also try lazy loading items using the lazy property

Flutter does not contain a 'id' or 'class' property and ‘queryselector’ like method to find the specific widget .

you can make use of keys as the id for the item.

If the above can not help, could you explain in detail the issue?

from fluent_ui.

The Widget structure of "items" in TreeView is nested while the data structure is plain.So map method is not the way to go .
This is a directory tree data .So TreeViewSelectionMode.multiple is necessary and I have to load all the data together ,lazy loading is not a way either.

So which method can i find a specific widget with a key?

from fluent_ui.

solved
