playwright/async_api/_generated.py:12963–12993

Page.expect_file_chooser Performs action and waits for a new `FileChooser` to be created. If predicate is provided, it passes `FileChooser` value into the `predicate` function and waits for `predicate(fileChooser)` to return a truthy value. Will throw an error if the page is

        Performs action and waits for a new `FileChooser` to be created. If predicate is provided, it passes `FileChooser`
        value into the `predicate` function and waits for `predicate(fileChooser)` to return a truthy value. Will throw an
        error if the page is closed before the file chooser is opened.

        Parameters
        ----------
        predicate : Union[Callable[[FileChooser], bool], None]
            Receives the `FileChooser` object and resolves to truthy value when the waiting should resolve.
        timeout : Union[float, None]
            Maximum time to wait for in milliseconds. Defaults to `30000` (30 seconds). Pass `0` to disable timeout. The
            default value can be changed by using the `browser_context.set_default_timeout()`.
