Backgroud: Currently we use Google Sheets to store data. We service clients and append their info into a single sheet (Its just a sinple row of data with name, phone number, email, payment method etc). We have a team of 5 people who do the work and input it in google sheets and we get max 10 customers daily.
Task: I want to make a Flutter Android application that my team can use to input the data into textfields and tap submit to append the info in this SQL database. The app should also be able to query data from the database. Rarely we will have to update the info as well.
Problem: I have made applications before with SwiftUI, CoreData, Flutter, local MySQL and JavaFX. My problem is that I'm not experienced with hosting databases and I'm not sure what services/techologies to use to connect this database with flutter. (I keep on hearing the terms php, apache, AWS RDS ...). I dont know where and how to host this database. How to integrate it with my application. Money isnt a constrant and I'll be happy to learn whatever I need to. I just would like to know what I need to do and where to start.
