CrossmintCheckoutLineItem class sealed

A single asset to purchase in a checkout order.

Use the named factory constructors to create line items:

• CrossmintCheckoutLineItem.collection — primary sale from a managed or imported collection. Supports optional callData for contract mint args.
• CrossmintCheckoutLineItem.token — secondary sale of a specific token, with optional callData for contract arguments.
• CrossmintCheckoutLineItem.tokenWithExecutionParameters — secondary sale (e.g. memecoin swap) with execution parameters controlling amount, mode, and slippage. Mutually exclusive with callData.
• CrossmintCheckoutLineItem.product — product-based purchase using a Crossmint product locator.
• CrossmintCheckoutLineItem.raw — forward-compatible escape hatch for line-item shapes not yet modeled by the SDK.

Constructors

CrossmintCheckoutLineItem.collection({required String collectionLocator, Map<String, Object?>? callData, Map<String, Object?> additionalFields})

Creates a collection line item for primary sales.

factory

CrossmintCheckoutLineItem.product({required String productLocator, Map<String, Object?> additionalFields})

Creates a product line item identified by a Crossmint productLocator. Use this for catalog-managed product purchases where the price and SKU are resolved server-side from the locator.

factory

CrossmintCheckoutLineItem.raw({required Map<String, Object?> value})

Forward-compatible escape hatch — passes value verbatim to the Crossmint orders API as the line item shape. Use when a new line-item field is not yet modeled by the typed factories above.

factory

CrossmintCheckoutLineItem.token({required String tokenLocator, Map<String, Object?>? callData, Map<String, Object?> additionalFields})

Creates a token line item for secondary sales with optional callData.

factory

CrossmintCheckoutLineItem.tokenWithExecutionParameters({required String tokenLocator, required Map<String, Object?> executionParameters, Map<String, Object?> additionalFields})

Creates a token line item with execution parameters for secondary sales (e.g. memecoins with slippage and amount control).
