Changelog

0.1.0

The first release of the Vezmo payment sheet for Flutter apps (vezmo_checkout), on Vezmo's native SDKs.

• API: VezmoCheckout(configuration: …), prepare(clientToken: …) or prepare(subscriptionToken: …), then present(). Neither throws. Results are a sealed class: CheckoutSucceeded, CheckoutProcessing, CheckoutCanceled, CheckoutFailed with a VezmoError (VezmoErrorCode and a message written for the buyer). One sheet at a time: present() while it is open is a config error.
• Android: the native Vezmo Android SDK's sheet (com.vezmo:vezmo-checkout 0.1.0): cards with 3D Secure, Google Pay, Klarna, Affirm, Afterpay, Amazon Pay, Cash App, UPI and Pix, the buyer's own currency, light and dark. The buyer comes back from bank apps and pay-later providers by themselves. Needs a FlutterFragmentActivity. A session prepared before the activity is recreated (a configuration change) is prepared again on the new one, so present() still opens it.
• Subscriptions: prepare(subscriptionToken: …) starts a subscription (the first payment, or a free trial with the card saved); the result carries subscription (ref, status), and paymentId is null for a free trial.
• Appearance: your colors (one, or light and dark), corner radius and a native font through VezmoAppearance.
• iPhone: the native Vezmo iOS SDK's sheet (Swift package VezmoCheckout 0.1.0, through Swift Package Manager): cards with 3D Secure, Apple Pay, pay-later methods, Cash App, UPI and Pix. The plugin hands links back into the app to the sheet by itself. Subscriptions too.
• Apple Pay and Google Pay merchant country from the session: the country of the account that processes the payment (the business's own on Connect, Vezmo's on merchant of record). merchantCountryCode on ApplePayOptions and GooglePayOptions is optional and only overrides it.
• Closing while UPI or Pix waits: the sheet asks Vezmo first. Paid meanwhile, it shows the receipt (CheckoutSucceeded); still waiting in the buyer's bank app, the result is CheckoutProcessing, never canceled, since the buyer can still approve it.
• No answer while paying (a timeout, a dropped connection): the sheet checks the session before reporting network, so a payment that went through is never reported as failed. A payment Vezmo already took stays the result even when the payment engine fails afterwards.
• Android: a payment in flight is never lost or doubled when the phone's settings change or the process is stopped.
• Test-mode badge: a darker orange behind its white text (5.2:1, up from 3.6:1), in light and dark.
• Android 7.0+ (API 24), iOS 15.1+; Flutter 3.41+.
