Flutter – How can I update value of likes variable in firebase?

DocumentReference tweetDocProfile = tweetsRef.doc(tweet.authorId).collection('userTweets').doc(tweet.id);
tweetDocProfile.get().then((doc) {
    int likes = doc.get('likes');
    tweetDocProfile.update({'likes' : likes+1});
});

Value of likes is not updating in Firebase, I am able to update it in code but update is not working I guess

    Try this!

    DocumentReference tweetDocProfile = tweetsRef.doc(tweet.authorId).collection('userTweets').doc(tweet.id);
tweetDocProfile.get().then((doc) { 
  int likes = doc.get('likes'); 
  tweetDocProfile.update({'likes' : int.parse(likes)+1}); 
});

    try this way, it is safer to modify,
    It saves you a get request and the script internally uses a transaction so it doesn’t overwrite the data.

    DocumentReference userTweetRef = tweetsRef.doc(tweet.authorId).collection('userTweets').doc(tweet.id);
userTweetRef.update({ likes: FieldValue.increment(1) });
