lawyer

A lightweight Flutter package to set business rules and obey

Without in need of a database or expensive queries
Getting Started #
The Lawyer creates lazy singleton class for storing rules and dimensions.
How to use:
final lawyer = Lawyer.instance;

lawyer.setRules(
[
Rule(Action.allow, [
"t-shirt",
["S", "M"],
"blue"
]),
Rule(Action.allow, ["jacket", "L", "black"]),
Rule(Action.allow, ["shoe", "46", "white"]),
Rule(Action.deny, ["shoe", "46"]),
Rule(Action.allow, ["shoe", "*", "*"]),
],
);

// This will return true
lawyer.check(["jacket", "L"]);

Usage with dimensions array:
final lawyer2 = Lawyer.instance;
lawyer2.setRules([
Rule(Action.allow, [
'Gold member',
['Mon', 'Tue', 'Wed', 'Thu', 'Fri'],
['Swimming pool', 'Gym', 'Sauna']
]),
Rule(Action.deny, [
'Guest',
['Mon', 'Tue'],
['Sauna', 'Gym']
]),
Rule(Action.allow, [
['Guest', 'Regular member'],
'*',
'*'
])
]);

const memberships = ['Gold member', 'Regular member', 'Guest'];
const days = ['Mon', 'Tue', 'Wed', 'Thu', 'Fri'];
const facilities = ['Swimming pool', 'Gym', 'Sauna'];

/// This will return true, because Guest is allowed for Saturday
lawyer2.check(['Guest', 'Sat']);

/// Set dimension arrays
lawyer2.setDimensions([memberships, days, facilities]);

/// After setting dimensions, this will return false,
/// Because we don't have any option for Saturday any more
/// Days dimension does not have Saturday!!
lawyer2.check(['Guest', 'Sat']);
