Add A New Payment Processor to a Flutter Project

Hi there! I need somebody to add a new payment processor to my Flutter project. Here’s a basic workflow

in Firebase only selected sellers can use this method for buyers to checkout

if enabled the sellers puts in their credentials in the seller options of the app ( selling options is in the app already )

than the seller can use this payment processor so buyers can pay them at checkout ( checkout is in the app already )

Here’s a link to how to set it up

Also I’m only looking to spend like 300 on this so keep that in mind.

Thx
