Flutter with Spring Boot Crash Course

Learn to build a Flutter search page with a scaffold, app bar, and a form containing two dropdown button form fields for selecting start and end cities, with validation.

Learn to build a Flutter search row with padding and a wide elevated button, use a global form key, validate two dropdowns, and show a departure date snackbar.

Define named routes with routes map, navigate from search page to search results page using pushNamed, and pass route and departure date in a list retrieved via modal route arguments.

Display bus schedules for a route in a Flutter app, showing bus name, type, departure date, and price, while fetching data asynchronously via a provider and route name.

Set up the seat plan page and navigate from a schedule item to the site plan page by passing the schedule and date, using a stateful layout with value notifier.

Build a dynamic seat plan view and seat widget in Flutter, using rows and columns in a scrollable view with stateful seats and neomorphic colors for available, selected, and booked.

Create a seat plan view in flutter by building a stateless seat arrangement widget with total seats, booked seat numbers, and business class flag, rendering rows and columns.

Learn to save a seat reservation on the seat plan page in Flutter with Spring Boot by building a customer and bus reservation, using a dummy data source.

Learn to implement a navigation drawer in flutter, enabling admin workflows to add bus, route, and schedule data, with a reservation view featuring an expandable list and time picker integration.

Learn how expansion panel list in Flutter works with header and body sections, an expanded state toggle, and item generation from a reservation model using dedicated header and body classes.

Explore how Spring Boot simplifies building production-grade Java applications with auto-configuration and an embedded Tomcat server, and learn to generate projects with Spring Initializr and Spring Web for REST endpoints.

Build rest endpoints in Spring Boot using path variables and get mapping to return json for a player pojo and a list of players.

Create a Spring Boot project from Spring Initializr with Lombok, Spring Web, Spring Data JPA, and MySQL driver, then build pojo entities like Bus using Lombok to reduce boilerplate.

Install and configure a local MySQL database, create the reservation schema, connect with Spring Boot via application.properties, and prepare entities and tables such as bus for the reservation backend.

Learn to implement a generic response model in Spring Boot, returning status codes, messages, and inserted objects (T) for operations like adding a bus, instead of raw strings.

Defines a bus route entity and table bus_route. Implements a JPA repository with find by route name and by city from and city to, a Spring Boot service and controller.

Test bus route APIs with Postman: add routes, fetch all routes, and query by route name or city pair, using Spring Boot controllers, services, and MySQL persistence.

Define a rest controller for bus schedule APIs with add, get all, and get by route name under /api/schedule, and verify them with Postman.

Fixes a backend reservation bug by correcting json property names, adding @RequestBody in the bus schedule controller, and leveraging JPA to fetch full bus and route objects without explicit joins.

Configure a security filter chain to distinguish open and restricted APIs by permitting all get requests and requiring authentication for others, using http security, request matchers, and basic authentication.

Explain a Flutter and Spring Boot authentication flow with json web tokens. Validate admin credentials, issue and store a jwt, and send it in authorization headers for each request.

Create a JWT auth filter that intercepts requests, retrieves a bearer token from the authorization header, validates it, loads user details, and updates the security context before the filter chain.

Update spring boot to 3.1.2 and refactor the security config to replace deprecated csrf and authorize http request with lambda or method reference, enabling admin login and JWT token.

Connect the Spring Boot backend to the Flutter app for admin login using HTTP and shared preferences, handling app user model, toJson/fromJson, and auth response.

Master Flutter admin login with spring boot API, troubleshoot responses and mapping, and prepare subsequent rest APIs using fromJson and the freezed library for automatic code generation.

Develop add bus API integration in Flutter, posting bus data to Spring Boot and using a response model. Handle authorization via token headers and express errors through error details model.

Implement the add route API in a flutter with spring boot app by mirroring the add bus flow, including url setup, auth headers, response modeling, and ui integration for schedules.

Launches api-driven search flow by collecting the start and end destination and a departure date, fetching a route object, and passing it to the search results page to retrieve schedules.

Learn api integration to save reservations from Flutter to a Spring Boot backend, using schedule id and departure date to post bookings and guide seat plan and confirmation.

Implement a reservation list page by fetching all reservations and filtering by mobile via api endpoints, with admin search and user versus admin views; note this is a prototype.
