Getting Started

To start using Feature Flagix, follow these steps:

1. Initialize Feature Flagix:

   import 'package:feature_flagix/feature_flagix.dart';
   
   // Create an instance of FeatureFlagix
   final FeatureFlagix featureFlagix = FeatureFlagix();
   

2. Define Roles and Permissions:

   import 'package:example/data/fake_flags.dart';
   import 'package:feature_flagix/feature_flagix.dart';
   
   // Define app roles
   enum Roles {
     user,
     admin,
     moderator,
     custom,
   }
   
   // Define feature flags
   enum Flags {
     feature1,
     feature2,
     feature3,
     feature4,
   }
   
   // Create a new instance of FlagixRoles with roles and permissions
   FlagixRoles flagixModel = FlagixRoles(
     roles: {
       Roles.user: FlagixPermissions<String>(
         permissions: [
           Flags.feature1.name,
           Flags.feature2.name,
         ],
       ),
       Roles.admin: FlagixPermissions(
         permissions: [
           Flags.feature1.name,
           Flags.feature2.name,
           Flags.feature3.name,
           Flags.feature4.name,
         ],
       ),
       Roles.moderator: FlagixPermissions(
         permissions: [
           Flags.feature1.name,
           Flags.feature2.name,
           Flags.feature3.name,
         ],
       ),
       Roles.custom: FlagixPermissions(
         permissions: customFlags,
       ),
     },
   );
   

3. Set Current Role:

   // Set the current role for the user
   featureFlagix.setCurrentRole(Roles.user);
   

4. Check Permissions:

   // Check if the user has a specific permission
   bool hasPermission = featureFlagix.hasPermission(Flags.feature1.name);
   

5. Update UI Based on Feature Flags:

   // Use FeatureFlagix to conditionally render UI elements
   Flagix(
     flag: Flags.feature1.name,
     child: const Card(
       child: ListTile(
         leading: Icon(Icons.person),
         title: Text('Feature 1'),
         subtitle: Text('This is Feature 1'),
       ),
     ),
   ),
