EnvManager<E extends Enum> class

Central coordinator for environment loading, switching, and persistence.

EnvManager is a controlled singleton. Access it via EnvManager.instance after calling EnvManager.init.

Type parameter E must be the user-defined enum that identifies environments (e.g. Environment).

Properties

allValues → List<E>: All registered environment values, in declaration order.
no setter
current → E: The currently active environment.
no setter
currentEnvData → Map<String, String>: All key/value pairs loaded for the current environment.
no setter
currentNotifier → ValueNotifier<E>: A ValueNotifier that broadcasts the currently active E whenever the environment is switched. Useful for reactive UI updates.
final
hashCode → int: The hash code for this object.
no setterinherited
isCurrentLocked → bool: Whether the currently active environment is locked.
no setter
persistSelection → bool: Whether the active environment is saved to and restored from SharedPreferences across sessions.
no setter
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited

get(String key) → String: Returns the raw string value for key in the current environment.
getBool(String key) → bool: Returns the value for key as a bool.
getDouble(String key) → double: Returns the value for key as a double.
getInt(String key) → int: Returns the value for key as an int.
getOrElse(String key, String fallback) → String: Returns the raw string value for key, or fallback if absent.
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
setPersistSelection(bool persist) → Future<void>: Changes the persist mode at runtime.
switchTo(E env) → Future<void>: Switches the active environment to env.
toString() → String: A string representation of this object.
inherited

init<E extends Enum>({required E defaultEnv, required Map<E, String> configs, Set<E>? lockedEnvironments, bool persistSelection = true, EnvLoader? loader, EnvStore? store}) → Future<EnvManager<E>>: Initialises the singleton with defaultEnv and the configs map.
instanceOf<E extends Enum>() → EnvManager<E>: Typed convenience accessor — returns this cast to EnvManager<E>.
reset() → void: Resets the singleton. Intended for testing only.
