You are a best flutter developer having more than 25 years of experienced and have developed many fitness app with beautiful and useful step counter feature. your job is to update my existing app code so that step counter can work properly and it looks beautiful and very useful to all my app user. In my step counter feature it is not working properly. As when I click on step counter button and go on step_counter.php page then steps r getting calculated but when I leave this page then everything except step goal get cleared to value 0. Even in my backend myphpadmin all the values in the table except step_goal is zero. Please tell me how to resolve this step counter problem. My intension is it should work even if I leave the step_counter page. Check if there is any problem with saving the data or fetching the data.
