Paperback. Condition: new. Paperback. Want to learn Flutter but feel overwhelmed by code, tools, and technical jargon?Flutter Cross-Platform App Engineering gives you a clear, beginner-friendly path from your first Flutter project to building practical applications for Android, iOS, web, and desktop.No prior Flutter or Dart experience is required. The book starts with the fundamentals and introduces each concept in a logical order, so you can build confidence without being buried in theory. Instead of learning isolated code snippets, you will develop a continuing application step by step and see how the pieces of a real project fit together. The manuscript is explicitly designed for complete beginners and developers new to Flutter. Flutter_Cross_Platform_App_Engi.Mistakes are treated as part of learning, not failure. Broken layouts, failed builds, unexpected behavior, and debugging problems are normal parts of software development. Each working feature, passing test, and solved problem becomes another small win that strengthens your skills and confidence. Flutter_Cross_Platform_App_Engi.Key FeaturesBeginner-friendly explanations of Flutter and DartA practical, continuing project that grows throughout the bookStep-by-step code presented in manageable sectionsResponsive and adaptive interfaces for different screen sizesNavigation, forms, routing, and application workflowsState management and maintainable app architectureREST API integration, JSON models, and reliable networkingLocal storage, caching, and offline-capable applicationsAuthentication, secure sessions, and application securityNative platform features, testing, debugging, accessibility, and performanceProduction builds for Android, iOS, web, Windows, macOS, and LinuxWhat You Will LearnBy the end of the book, you will understand how to move beyond simple Flutter examples and build a structured cross-platform application with clear architecture, responsive interfaces, routing, shared state, networking, persistence, authentication, platform integration, automated testing, and production delivery. Flutter_Cross_Platform_App_Engi.You will also learn how to think like a developer: how to organize responsibilities, investigate problems, test important behavior, handle platform differences, protect sensitive data, and prepare applications for real-world release.Who This Book Is ForThis book is for: Complete beginners starting with Flutter and DartSelf-learners who want a structured learning pathStudents exploring mobile and cross-platform developmentDevelopers moving into Flutter from another language or frameworkAnyone who wants to build practical apps instead of only following short tutorialsTable of ContentsChapter 1: Engineering Modern Applications with FlutterChapter 2: Responsive and Adaptive User InterfacesChapter 3: Navigation, Routing, and Application WorkflowsChapter 4: Application Architecture and State ManagementChapter 5: APIs, Models, and Reliable NetworkingChapter 6: Local Persistence and Offline-Capable ApplicationsChapter 7: Authentication and Application SecurityChapter 8: Platform Integration and Native CapabilitiesChapter 9: Testing, Debugging, and Application QualityChapter 10: Building and Shipping for Production Flutter_Cross_Platform_App_Engi.If you are ready to stop feeling intimidated by app development and start building with confidence, Flutter Cross-Platform App Engineering gives you the practical guidance and supportive structure to begin.Start your Flutter Shipping may be from multiple locations in the US or from the UK, depending on stock availability.…

Paperback. Condition: new. Paperback. Building real backend systems can feel overwhelming when tutorials jump too quickly from "Hello World" to databases, security, microservices, messaging, containers, and cloud deployment. Spring Boot 4 Microservices Engineering gives you a clearer path.Designed for Java developers who are new to Spring Boot, backend engineering, or microservices, this practical guide walks you through the process one manageable step at a time. You do not need previous experience with Spring Security, PostgreSQL, Kafka, Docker, Kubernetes, or distributed systems. Basic familiarity with Java is helpful, and every major Spring and backend concept is introduced progressively.Instead of disconnected examples, you build one evolving commerce and fulfillment platform and gradually transform it into a secure, persistent, event-driven, observable, tested, and deployable distributed system.Key FeaturesStep-by-step explanations that break complex backend concepts into manageable stagesPractical Java and Spring Boot 4 examples built around a real projectProduction-focused REST API development, persistence, security, testing, and deploymentHands-on coverage of PostgreSQL, JPA, Hibernate, OAuth2, JWT, gRPC, Kafka, Docker, Kubernetes, and observabilityPractical exercises that reinforce each chapterClear explanations of common failures, troubleshooting, and why engineering decisions matterA learning approach that treats mistakes as part of the process and builds confidence through small, working improvementsWhat You Will LearnYou will learn how to: Build structured Spring Boot applications with clear architectural boundariesDesign, validate, document, and test production-ready REST APIsPersist data safely with PostgreSQL, Spring Data JPA, Hibernate, and migrationsSecure APIs with Spring Security, OAuth2, OpenID Connect, JWT, roles, and permissionsDesign and decompose microservices with clear service and data ownershipCommunicate between services using HTTP, gRPC, and Apache KafkaHandle retries, idempotency, eventual consistency, circuit breakers, and failure scenariosAdd structured logging, metrics, health checks, and distributed tracingTest realistic infrastructure with integration and contract testingContainerize services with Docker and deploy them with KubernetesWho This Book Is ForThis book is ideal for Java developers, students, self-learners, and aspiring backend engineers who want to move beyond basic tutorials and understand how modern services are actually designed, secured, tested, observed, and deployed.
