Learmond Pay Element with Source— lpe_with_source

This package provides a styling-focused Source pay button and convenience wrappers around the published paysheet UI so apps can present a consistent paysheet and native device-pay flows.

Quick start #

Add the package to your pubspec.yaml and import the public barrel:

import 'package:lpe_with_source/lpe_with_source.dart';

The package re-exports the core paysheet helpers and common widgets:

• presentPaysheet(...) / showLpePaysheet — present the paysheet UI (publishable key is optional)
• StripePaymentResult — result type returned from the paysheet
• LearmondPayButtons — re-exported from package:lpe for the single-line pay buttons
• Source and SourcePayButton — the styling-first Source button API provided by this package

Source button (recommended for styling-only integration) #

This package exposes a single-instance Source helper to provide default styles and convenience factories:

• Source.present — mutable singleton with defaultStyle and defaultPublishableKey.
• Source.present.source_pay_button() — returns a SourcePayButton built with the singleton defaults.

If you need per-button overrides, instantiate SourcePayButton directly:

SourcePayButton(
	style: Source.present.defaultStyle,
	amount: '24.99',
	merchantArgs: {
		'merchantName': 'My Store',
		'merchantInfo': 'Order #123',
		'summaryItems': [
			{'label': 'T-shirt', 'amountCents': 1999},
			{'label': 'Shipping', 'amountCents': 500},
		],
	},
	onResult: (result) { /* handle result */ },
)

Notes:

• merchantArgs['summaryItems'] should be a List of maps with label (String) and amountCents (int). Native pay sheets will render these as Line Items.
• The package does not require a publishable key for styling. presentPaysheet(...) and SourcePayButton accept optional

LearmondPayButtons #

If you want the bundled single-line pay buttons, you can import and use LearmondPayButtons directly (this package re-exports it from package:lpe):

LearmondPayButtons(
	amount: '9.99',
	onResult: (r) { /* handle StripePaymentResult */ },
)

Example app #

See lpe_with_source_test_app/ for a small demo that shows SourcePayButton usage and how to pass merchantArgs.summaryItems to display Line Items in native pay flows.

Notes #

• This package is intentionally styling-focused — it provides a consistent Source button and convenience re-exports. Use presentPaysheet or the LearmondPayButtons widget for presenting the paysheet and native device pay flows as appropriate.
