keygrant 0.1.1

KeyGrant licensing for Flutter apps: offline-verified leases, trials, licence files, metered uses and key pickup, on iOS, Android, Windows, macOS and Linux.

Changelog

0.1.1

• Documentation only, no code change: selling through Paddle, the upgrade link is your own checkout page, which reads client_reference_id from its address and gives it to Paddle.js as custom data under the same name. The README says how.

0.1.0

• The first release of the KeyGrant Flutter plugin, for iOS, iPadOS, Android, Windows, macOS and Linux: a port of the reference Electron SDK held to the SDK contract and every group of the shared conformance vectors.
• KeyGrantLicense: status(), refresh(), activate() (with a user-locked key's email and code), deactivate(), startTrial(), upgradeUrl(), has() and require(), use() for metered uses, importLicenseFile() and importLicenseFileBytes() with removeLicenseFile(), and key pickup: pickUp(), confirmPickUp() and restoreByEmail(), for an App Store build that restores a web buyer's licence by email.
• Leases verified offline against the product's key set; trials with an anti-reset start; the clock guard; renewals, refusals and their waits; offline licence files; the journal of metered uses spent with no answer. status(), refresh(), startTrial(), has(), use() and the pickup calls never throw.
• Fingerprints: the registry API on Windows, IOKit on macOS (through the plugin), the machine-id files on Linux; on iOS an install id in the Keychain, on Android ANDROID_ID. The iOS Keychain also keeps a trial's start.
• Default storage: one JSON file per product in the platform's folder, written atomically.
