I tried installing the same module in windows also but getting a similar error in that too....not sure what the problem is...

Updated the question title and details as now my problem is I am not even able to install the flask-mysqldb. earlier I was getting only import error for this package.

Please suggest any solution...it been three days now...even reinstalled ubuntu but still got no solution.

first doing

pip3 install wheel

followed by doing

sudo apt-get install build-essential libssl-dev libffi-dev python3-dev

solves the problem. Thankyou @rtaft for suggesting the answer.
