In order for you to disable a button, you need to set it to null

 resendbutoonfunction() {
        print("hello");
        setState(() {
          _enable1=false;
          mycolo=Colors.grey;
        });
      //  timer = Timer.periodic(Duration(seconds: 5), (Timer t) =>disable());
       // _controller.forward(from: 0.0);
      //  timer = Timer.periodic(Duration(seconds: 4), (Timer t) =>timertest());
      }

Then for your button:

onPressed: _enable1 ? resendbutoonfunction : null,

As far as I understand your code, as you wrote it, the test (if _enable1), and therefore the definition of the function, is executed only once.

Either the test must be inside the function :

resendbutoonfunction=() {
 if (_enable1) {
    ...
 }
}

Or, if your code is executed regularly, then you can change the definition of resendbutoonfunction

if(_enable1) {
  resendbutoonfunction=() {
    print("hello");
    setState(() {
      _enable1=false;
      mycolo=Colors.grey;
    });
  //  timer = Timer.periodic(Duration(seconds: 5), (Timer t) =>disable());
   // _controller.forward(from: 0.0);
  //  timer = Timer.periodic(Duration(seconds: 4), (Timer t) =>timertest());
  };
}
else {
  resendbutoonfunction=() {
     // do nothing
  }
}
