Error at snapshotData.docs[index].data()['firstName'] flutter-CodePudding

I am trying to implement Searchbar for my application which will search according to user's firstName.
I am facing the below error saying

The method '[]' can't be unconditionally invoked because the receiver can be 'null'.
Try making the call conditional (using '?.') or adding a null check to the target ('!').

Code

late QuerySnapshot snapshotData;
..
..
title: Text(snapshotData.docs[index].data()['firstName'], style: TextStyle(
            color: Colors.white,
            fontWeight: FontWeight.bold,
            fontSize: 24.0
          ),
          ),

CodePudding user response：

Use

Text(snapshotData.docs[index].get('firstName'))
