I’m Android Developer and I’m working in a software company in Vietnam. I have experience in both kind project: outsourcing project and product project. I decided to study Flutter, because I believe it’s promised in future. As experienced developer, I care about clean architecture, testing, performance and maintainability that why I keep searching for an example of completed application. Unfortunately, community now full of project such as speedcode, UI challenges, … it’s just small pieces of real world application. In fact, most of the project doesn’t have fancy UI like that. That why I build this project by myself and now share it to the community, I hope you can get something from it then apply to your work.
The first version of project (v1.0) is just about UI + simple logic. In this version v2.0, I applied BloC pattern by using Flutter Bloc to project and also have unit tests for it. I also built simple Mock API for the app, it just static json file uploaded to a my private hosting. I hope I have time to do cache local data by SQLite but I have not, so hope next version will be soon available.
In Home screen, it just simply load then show data to UI. What you can try
- (0) is about me :D
- (1) is carousel slider for displaying banners, it’s automatically animate each 1 second. You can swipe left or right to see next/previous item
- (2) is list seat categories. If you click on a category, app will open All shows screen. It’s horizontal list so you can swipe to reach more item
- (3) is recommended seats. Click on item app will open Show details screen
- (4) is nearby theatres. There’s nothing special to try here, it’s just simple map with highlighted cine’s locations
- (5) (6) is list shows by each category. Same with recommended seats, you can click on item to open Show details screen
- (1) click to open search field. Basically support search by name
- (2) click to open sort option. Basically support sort by rating and name
- (3) there’re 3 tabs: Now showing, Coming soon and Exclusive. You can swipe left/right to view content of each tab
- (4) Display list show in gridview
- Sort options dialog
- App will perform search after stop typing for 400 milliseconds, technically it’s debounce technique. Try to click on item, app will open Show details screen
- (1) is trailer of show from Youtube link
- (2) show’s description
- (3) is offer section. This is not static content, it can be changed in mock API
- (4) is user’s review section. Basically write review function is not available yet
- (5) is casts section. It’s horizontal listview, you can swipe to reach more content.
- (6) Click Book seats then app will open Book Time Slot screen
- (1) Click to open search field. Basically support search by Cine’s name
- (2) List cine with time slots. Gray item is time slot that is not available.
- App will perform search after stop typing for 400 milliseconds, technically it’s debounce technique. Click on item time slot, app will open Book Seat Type screen.
- (1) choose number of seats
- (2) choose seat type
- (1) is count of number booked seats
- (2) Booked seats. You can click to select then click again to deselect seat.
- Validate: For example in screen Book Seat Type you chosen 3 seats, type is Jack that mean
- You cannot select Queen or King seat
- You cannot book more than 3 seats
- App integrated with Stripe SDK, currently for testing when you click on any method Debit/UDI/Net banking, app only show option pay by input card to the form.
- For testing, please use following information:
- Card number: 4242 4242 4242 4242
- Expiration date: 04/24
- CVC: 424 or 242
- After Stripe verified the payment information, app will show your booking information.
- Basically app provide login by user’s email and password. Login by Google and Facebook will be available soon.
- Test account: khoaha+dev2@mailinator.com / 123456
- I did validation in this form using Bloc pattern, you can look at this to study how to do form validation in Bloc.
