Hello Paul
I am very fond of your tutorial. Right now I have finished chapter 3.
And though rustc gives me the correct hint, I would prefer your tutorial to be complete.
regarding main.rs:
It took me some attempts to figure out where to write the two lines
and second the following line is missing (I put it in line 2)

use crate::data::TodoItem;

Please add this to your doc
Thanks
Michael

Hello Paul
Now I am finished and though I yet not fully understand why you did some of the programming, it gives me serious clues how to structurize my own apps.
In chapter 7 you didn't finish the Flex correct.

you wrote:
Flex::row()
.with_child(checkbox)
.with_child(label)
.with_flex_spacer(1.)
.with_child(delete_button)
.controller(TodoItemController
let delete_button = Button::new("Delete").on_click(TodoItem::click_delete);

But the last line should be removed and replaced just by a closing ")"

Thanks for your work!

Hi everyone, i want to use the disable_if method to Enable\Disable my widgets when data.value is true.
I saw https://github.com/linebender/druid/pull/1702/files# pull request but i don't understand how to use the method.
let spinner_section = Flex::column() .with_child(Label::new(LocalizedString::new("Sto cercando gli schemi...")).with_text_color(Color::BLUE).padding(5.0)) .with_child(Spinner::new().with_color(Color::BLUE)) .disabled_if(|data: &mut AppState, _env: &Env| data.processing) .padding(40.0);
On disable_if method gave me an error: type mismatch in closure arguments
expected signature of for<'r, 's> fn(&'r _, &'s Env) -> _

Someone can help me to understand how to use this feature? Thanks in advance.

In README.md, on line 389, we have some code injection:

Make sure to declare the new modulepub fn new(todos: Vec<TodoItem>) -> Self {
        Self {
            new_todo: "".into(),
            todos: Vector::from(todos),
        }
    }s:

Very vulnerability!
