VirtualKeyboard class
A stateful widget that represents a virtual keyboard.
The VirtualKeyboard widget provides a customizable virtual keyboard interface that can be used in Flutter applications. It allows users to input text using an on-screen keyboard, which can be useful for devices without a physical keyboard or in scenarios where a virtual keyboard is more appropriate.
The widget is configured using the KeyboardConfigController and KeyboardViewInsetsState parameters, which control the behavior and appearance of the keyboard. The decorations parameter can be used to customize the appearance of the keyboard keys.
The maxKeys parameter sets the maximum number of keys that can be displayed on the keyboard, while the maxHeight parameter sets the maximum height of the keyboard. The keyPadding and keyboardPadding parameters control the padding around the keys and the keyboard, respectively.
