I have created my website using Java Enterprise Edition (JSP/Servlets) and MySql 8 for my database. It is a typical CRUD application with a feature that let the user track the car's location. I thought of using Flutter since it will save me time with its cross-platform capabilities but I have'nt found any documentations that will make the user login from the app to my website and fetch some data. I'm pretty sure it is possible somehow. Otherwise is there a way to simulate my website as fast as possible without using Chrome obviously.
