Parameters

label (str)

A short label explaining to the user what this widget is used for.

key (str or int)

An optional string or integer to use as the unique key for the widget. If this is omitted, a key will be generated for the widget based on its content. Multiple widgets of the same type may not share the same key.

help (str)

A tooltip that gets displayed next to the camera input.

on_change (callable)

An optional callback invoked when this camera_input's value changes.

args (tuple)

An optional tuple of args to pass to the callback.

kwargs (dict)

An optional dict of kwargs to pass to the callback.

disabled (bool)

An optional boolean, which disables the camera input if set to True. The default is False. This argument can only be supplied by keyword.

Returns

(None or UploadedFile)

The UploadedFile class is a subclass of BytesIO, and therefore it is "file-like". This means you can pass them anywhere where a file is expected.
