As you have mentioned having 2 years of knowledge of working with flutter is enough to get jobs in various companies. There are companies that do allow candidates with 1 year of experience even.
The requirements for a Flutter, which involves handling the Android & IOS stack of the company. would prefer someone who knows how to get the most out of it, or someone who has similar experience in any other comparable framework like Android, React Native.
If you are interested and have a good command of knowledge on Dart, IOS development, and Andriod, there is no one who can stop you from getting a job.
Hope the above information helps!!
