I'm new to flutter, so basically I'm making a product selling app and the products will be inserted by the customer, so my question is how can I translate all the texts in the app in a click of a button (The text in the app itself and the texts in which the customers gonna name the product eg- book), iv gone through many packages but most translate only a string and other are hard coded in json files, Help will be much appreciated , Thank you.
