UpdatePolicy class

Decides whether the running app should update.

Extend or compose this to plug in custom rules (staged rollouts, kill switches, per-country gating, etc.).

Constructors

UpdatePolicy({PrismVersion? minimumVersion, Set<UpdateChannel> channels = const {UpdateChannel.stable}, int rolloutPercent = 100, String? rolloutDeviceId})

Creates a policy.

const

UpdatePolicy.fromJson(Map<String, dynamic> json)

Builds a policy from a remote configuration map, e.g.:

factory

Properties

channels → Set<UpdateChannel>

Channels considered when resolving the latest version.

hashCode → int

The hash code for this object.

no setter, inherited

minimumVersion → PrismVersion?

Below this version an update is forced. null disables forced updates.

final

rolloutDeviceId → String?

Device/installation identifier used for rollout bucketing. When null, rollout gating treats the device as included (useful for tests).

final

rolloutPercent → int

final

runtimeType → Type

A representation of the runtime type of the object.
