title: SMS Receiving and Sending in Flutter Application
body: <p>I am building a flutter app in which i want to capture incoming sms. I searched on pub.dev and found few packages offering similar functionality i.e. sms_maintained and sms_retreiver etc. I tried them but i am not satisfied with the provided functionality. I need more control such as listening to incoming sms messages while app is not running and manual control to start and stop listening for messages. So, i am thinking of writing own SMS handling code from scratch instead of using a package. I want guidance to achieve this. i.e. where to start???
  I am new to flutter and mobile app dev, i don't know whether my question is worthy of being answered or not, that's why i am asking.</p>
