'How to pass Json data from one dart file to another?
I am trying to pass JSON data from Scryfall from my results.dart to display on my wishlist.dart after clicking the shopping bag button. I have no clue how to go about it. I mainly just want to display the name of the card, and the price. If i could get some help in the next hour, that'd be great! Here is the code: RESULTS.DART:
