Function returns null

var result;
  
void searching() async{

  var searchData = await FirebaseFirestore.instance.collection('users').where('email',isEqualTo: userEmail).get();
  
    setState(() {
      result = searchData.docs.first;
    });
  }

  
void addFollowing(var username , var email , var phoneNumber) async{
  searching();
  await FirebaseFirestore.instance.collection('users').doc(result).collection('following').doc().set({
    'username':username,
    'email':email,
    'phoneNumber':phoneNumber
  });
  print(result);
}

I have two function searching and addfollowing . The searching function returns a document that matches the given email and sets the id of that document in result . But it returns null for some reason when i call that fucntion in the addfollowing function .

I am using the add following function on an onTap of a gesturedetector. The first press returns null but the second press returns the data .

>Solution :

the searching is not complete then yet. you need to await it. So change

searching();

to

await searching();

Also, I believe you need to change this

void searching() async{

to this as well

Future searching() async{
