Gini class final

A class that represents a Gini coefficient.

The Gini class is a simple value object that represents a Gini coefficient. It consists of an int value that represents the year of the Gini coefficient, and a double value that represents the value of the Gini coefficient. The year field must be greater than 1990, and the coefficient field must be between 0.0 and 100.0 (inclusive). Reference - https://wikipedia.org/wiki/Gini_coefficient.

Example usage:

final gini = Gini(year: 2020, coefficient: 32.0);
print(gini.year); // Prints: 2020
print(gini.coefficient); // Prints: 32.0
