Answer 1

Arrow Function can run single statement function.

Options:

1 - You can run two Functions as Below.

RaisedButton(
               color: Colors.blueAccent, 
               onPressed: () {
               sendData(); //fun1
               signupPage(context); //fun2
               },
               child: 
                Text("Signup"),
             )

Or

2 - You can run fun2 in fun 1.

RaisedButton(
               color: Colors.blueAccent, 
               onPressed: () => sendData(context), //fun1
               child: 
                Text("Signup"),
             )

void sendData(BuildContext context){
//sendData Code ...
signupPage(context); //fun2
...
}
