FeatureFlagCondition class final

A condition configuration that evaluates feature flags for dynamic behavior.

Features:

• Multiple data type support (string, number, boolean, JSON)
• Integration with feature flag service
• Asynchronous evaluation
• Type-safe value handling

Example:

// String flag
final condition = FeatureFlagCondition(
  flagName: 'app.theme',
  dataType: FlagDataType.string,
);

// Boolean flag
final condition = FeatureFlagCondition(
  flagName: 'feature.enabled',
  dataType: FlagDataType.boolean,
);

// In a conditional content
final conditional = Conditional(
  condition: Condition(
    configuration: FeatureFlagCondition(
      flagName: 'feature.enabled',
      dataType: FlagDataType.boolean,
    ),
  ),
  cases: [
    CaseItem(
      value: 'true',
      item: FeatureContent(),
    ),
  ],
  defaultCase: 'false',
);

The condition:

• Returns null if flag name is empty
• Converts all values to strings for case matching
• Handles JSON values by encoding them
