I am new to coding and have been working on a group project to develop a flutter application. Our application needs to have the functionality of sending SMS to a mobile number (by tapping an option on the screen) through an online server. Online server needs to send the message so that the user does not have the message history in their phone (as I am working for domestic violence victims, their phones are regularly checked by the perpetrators). Both the message and the recipients information will be stored on an online database which we intend to connect with our application. Please guide me as at how I should approach this application. Thank you.
