We can access using keypath. The library ensures safe type checking and casting, and use provided default value as last resort
final String byProperty = resolve(json: json, path: "movie", defaultValue: "error");
expect(byProperty, "isFun");
final int byInt = resolve(json: json, path: "earth", defaultValue: 0);
expect(byInt, 199999);
final String byIndex = resolve(json: json, path: "dc.2.name", defaultValue: "error");
expect(byIndex, "Wonder Woman");
final String byIndexThenProperty = resolve(json: json, path: "marvel.0.appear.1.title", defaultValue: "error");
expect(byIndexThenProperty, "The Dark World");
