I suggest you drop the if/else condition and use a switch to check for the ConnectionState.

switch(snapshot.connectionState){
  case ConnectionState.waiting:
    return Center(child:CircularProgressIndicator());
    break;
  default:
    if(snapshot.hasError){
       // Handle errors
     }else if(!snapshot.hasData){
       // Handle no data
      }else {
       // Check for null
       var result = snapshot.data
       if(result!=null){
         //Handle the null value
       } else {

        }
      }

    break;
