Custom code block for Tapcart mobile app

Description

Hello, thank you for taking the time to review our posting. We need you to develop a Custom Code Block for the Tapcart Mobile App. Tapcart is a service/platform that allows us to easily launch our Shopify store as a mobile app. Their native features are limited, but they allow us to develop Custom Code Blocks. Tapcart Custom Code Blocks documentation https://docs.google.com/document/d/1kukMFmy-muGv5jrIosyVjOlOHeeQAytLnhWtMUo0d_A/edit?usp=sharing Custom Code Blocks will provide a dev environment similar to CodePen. One feature we use on our website/app is more than 3 options/more than 100 variants. For the website, we use an app called Product Variants Reloaded (PVR). PVR app combines multiple Shopify products on a single webpage so it appears to the user as a single product. We want this same functionality on Tapcart. We need you to develop a Custom App block for the Tapcart product form to use the JSON in the product metafields from the PVR app for multiple option products. - use the metafields from the PVR app - show dropdowns and selectors in the native Tapcart fashion - be a selectable template for specific products This block should behave similarly to the Product Variants Reloaded App which we currently use for our website. The developer needs to be proficient in HTML, CSS, and Java to build the variant selector functionality required. The developer needs to know how to make an API call to hit Shopify and extract the data to render the variant info in the PDP. Then they will need to build logic to ensure the customer selects all three variants before the add-to-bag button enables.
