Extensions

ColorExt on Color
FragmentResourcesExt on Resources
ListBrackets on List
ListExt on List<E>
MapBrackets on Map<String, dynamic>
A simple utility for retrieving data using dot/bracket notation. As long as your data follows a simple convention you can use a simplified dot/bracket notation to locate any piece of data in your hierarchy. Searches return null if no data is found or if the path string is invalid.
