ThemeDecoder class

Decoder capable of converting JSON compatible values into Flutter Theme related classes and enums.

All decoder functions, in addition the the type that can be decoded, will accept a value of the returned type and return it unmodified. However, when mixing JSON compatible values and concrete values, you must disable the JSON Schema validator as it will not be able to validate concrete instances.

Unless otherwise stated, each function will return null when given an input of null.
