Restaurant Ratings example - JSON Serialization code.While the example JSON we used as reference wasn't too complex, we still ended up with a considerable amount of code: consider using the deep_pick package to parse JSON in a type-safe way.for nested JSON data (lists of maps), apply the fromJson() and toJson() methods.add explicit casts, validation, and null checks inside fromJson() to make the parsing code more robust.create model classes with fromJson() and toJson() for all domain-specific JSON objects in your app.When null, JSON objects will be returned as. When true, JSON objects will be returned as associative array s when false, JSON objects will be returned as object s.

You need to write the parsing code that is most appropriate for your use case. This specific implementation makes some assumptions about what may or may not be null, what fallback values to use etc.

if the reviews are missing, we use an empty list ( ) as a fallback.

map() operator to convert each dynamic value to a Review object using omJson()

the values in the list could have any type, so we use List.

the reviews may be missing, hence we cast to a nullable List.
