InputDecorationTheme class Null safety

Defines the default appearance of InputDecorators.

This class is used to define the value of ThemeData.inputDecorationTheme. The InputDecorator, TextField, and TextFormField widgets use the current input decoration theme to initialize null InputDecoration properties.

The InputDecoration.applyDefaults method is used to combine a input decoration theme with an InputDecoration object.
