Getting input value

[neoacevedo]

A simple question: How do I get the value of an input in the onInput event?

[schultek]

The onInput callback gets a parameter, which is the value of the input element.

The type depends on the kind of input:

/// - `bool?` for checkbox or radio input elements
/// - `num?` for number input elements
/// - `DateTime` for date input elements
/// - `List<File>?` for file input elements
/// - `List<String>` for select elements
/// - `String` for text input and textarea elements
/// - `Null` for all other elements

So e.g.

input(type: InputType.checkbox, onInput: (checked) {
  assert(checked is bool?);
});
