Household account book app
There is a userTranscation list in main.dart, and it creates an expense list. Like the quiz app, all functions and variables are defined in the MyhomePage class and passed to the related widget.
Send a list of expenses from the last 7 days to the Chart widget, and create a chart with CharBar.
Send expenditure list and expenditure details deletion function to TransactionList widget, and create ListView.
If you click the app bar and the float button at the bottom, the ModalBottomSheet function is executed. Send the expense details addition function to NewTransaction, and create an input window.

In MyApp, functions such as filtering and adding favorite, filtered meals list, and favorite meals are defined. The function and the prepared meal list are transmitted to each screen through Navigation.
The default view is TabScreen. With the navigator at the bottom you can go to the whole category or the list of favorite meals.
The entire category receives and writes dummy data, and creates a separate category item to complete the grid. Clicking on a specific category brings up a list of meals that belong to that category.
If you click on one of the lists, you will be taken to the detail page and you can like it there.
Filtering can be set in Drawer.
