Using tab to indent should work.

If you want to extend more blocks to support indent, you can add the types into this array.

final indentableBlockTypes = {
  BulletedListBlockKeys.type,
  NumberedListBlockKeys.type,
  TodoListBlockKeys.type,
  ParagraphBlockKeys.type,
};

I was searching for an easy way to programmatically increase/decrease indentation for a selection in the mobile app, using custom toolbar actions

[TatsuUkraine]

I build own logic to update delta in the editor on button click since I didn't find sort of like a command, where you can pass selection, so it could update list items indentation for me, similar to toggleAttribute or formatNode

[LucasXu0]

You can execute the command directly, but it relies on the selection. You must set a selection before executing this command.

indentCommand.execute(editorState);
