bool docExists = await checkIfDocExists('document_id');
print("Document exists in Firestore? " + docExists.toString());

/// Check If Document Exists
Future<bool> checkIfDocExists(String docId) async {
    try {
      // Get reference to Firestore collection
      var collectionRef =
          FirebaseFirestore.instance.collection('collectionName');

      var doc = await collectionRef.doc(docId).get();
      return doc.exists;
    } catch (e) {
      throw e;
    }
  }
//Good luck, firebase and flutter are awesome ;)
