AccessPolicy class

Maps named features to the minimum MembershipTier required to access them.

Define the policy once at startup and consult it wherever access-control decisions are needed:

final policy = AccessPolicy();
policy.define('export_pdf',  MembershipTier.pro);
policy.define('sso',         MembershipTier.enterprise);

// Check a specific user's tier:
if (policy.canAccess('export_pdf', userTier)) {
  exportToPdf();
}

// List everything a pro user can do:
final features = policy.featuresAvailableTo(MembershipTier.pro);

Constructors

AccessPolicy()
Creates an empty policy. Features must be defined before querying.

Properties

allDefinedFeatures → List<String>
Returns all explicitly defined feature names.
no setter
hashCode → int
The hash code for this object.
no setterinherited
isEmpty → bool
Whether the policy has no defined features.
no setter
length → int
The number of features defined in this policy.
no setter
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
snapshot → Map<String, MembershipTier>
Returns a copy of the underlying policy map (immutable snapshot).
no setter

Methods

canAccess(String featureName, MembershipTier userTier) → bool
Returns true if userTier meets or exceeds the required tier for featureName.
clear() → void
Removes all defined features (useful in tests).
define(String featureName, MembershipTier requiredTier) → void
Registers featureName as requiring at least requiredTier for access.
defineAll(Map<String, MembershipTier> definitions) → void
Registers multiple definitions at once.
featuresAvailableTo(MembershipTier tier) → List<String>
Returns all feature names that tier can access given this policy, including features that are open (undefined) would need to be known externally — this method returns only explicitly defined features that tier qualifies for.
featuresLockedFor(MembershipTier tier) → List<String>
Returns all feature names that tier cannot access.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
requiredTierFor(String featureName) → MembershipTier?
Returns the minimum MembershipTier required to access featureName, or null if the feature is not in the policy (open access).
toString() → String
A string representation of this object.
inherited
undefine(String featureName) → void
Removes a previously defined feature from the policy.

Operators

operator ==(Object other) → bool
The equality operator.
