1 - Singleton Pattern: Ensures a class has only one instance and provides a global point of access to it. Useful for managing shared resources.
2) Factory Method Pattern: Defines an interface for creating objects, allowing subclasses to alter the type of objects that will be created. This promotes loose coupling.
3) Abstract Factory Pattern: Provides an interface for creating families of related or dependent objects without specifying their concrete classes. It’s useful in managing multiple object creation scenarios.
4) Builder Pattern: Separates the construction of a complex object from its representation. Builder allows for step by step construction and can create different representations.
5) Prototype Pattern: Allows creating object copies or clones without specifying their full class. It is particularly useful when the cost of creating a new instance is costly.
6) Adapter Pattern: Converts the interface of a class into another interface clients expect. It allows classes to work together that could not otherwise because of incompatible interfaces.
7) Bridge Pattern: Decouples an abstraction from its implementation, allowing both to vary independently. It is useful in situations where implementations can change frequently.
8) Composite Pattern: Composes objects into tree structures to represent part whole hierarchies. Clients can treat individual objects and compositions of objects uniformly.
9) Decorator Pattern: Enables adding new functionality to an object dynamically without altering its structure. It provides a flexible alternative to subclassing for extending functionality.
10) Facade Pattern: Provides a simplified interface to a complex subsystem. It hides the complexities of system and provides an interface that makes the subsystem easier to use.
11) Flyweight Pattern: Reduces the cost of creating multiple similar objects by sharing common parts of the state. It’s used to optimize memory usage in systems.
12) Observer Pattern: Defines a one to many dependency between objects so that when one object changes state, all its dependents are notified and updated automatically. Useful in event based systems.
13) Strategy Pattern: Enables selecting an algorithm’s behavior at runtime by encapsulating the algorithm in a separate class. It promotes the idea of using interchangeable algorithms.
14) Command Pattern: Turns a request into a stand alone object that contains all information about the request. This pattern is useful for queuing requests, logging the requests, or supporting undo operations.
15) Template Method Pattern: Defines the program skeleton of an algorithm in an operation, deferring some steps to subclasses. It allows subclasses to redefine certain steps of an algorithm without changing its structure.
16) Chain of Responsibility Pattern: Passes requests along a chain of handlers, where each handler decides either to process the request or to pass it to the next handler in the chain.
17) State Pattern: Allows an object to alter its behavior when its internal state changes. The object will appear to change its class, making state management easier.
These design patterns provide essential solutions for common problems encountered in software design, specifically in Java applications. The training program will cover theoretical concepts and practical implementations, enabling students to design more robust and maintainable applications.

I am learning flutter from JustAcademy, They provide very much great environment where people gather and work simultaneously. totally project based training institute.
Awesome Experience. I am a Front-end Web Designer working at Star India for 3 years now. I applied for Full-stack development and my experience has been phenomenal & they really do help with placements exceptionally. Thank you Roshan sir so much.
Flutter app monitoring with Prometheus and Grafana delivers real-time observability by instrumenting the app (via OpenTelemetry or lightweight exporters) to expose metrics that Prometheus scrapes and stores as time-series data. Grafana visualizes those metrics in customizable dashboards and triggers alerts, letting teams track CPU/memory, frame-render times, network latency, error rates and user-impacting regressions. This stack helps quickly detect performance problems, diagnose root causes, and continuously improve app stability and user experience.
Flutter CI with Codemagic is a cloud-first continuous integration and delivery solution that automates building, testing and releasing Flutter apps across iOS, Android and web using configurable workflows (codemagic.yaml), hosted macOS/Linux runners, dependency caching and parallelization. It integrates with GitHub/GitLab/Bitbucket, manages code signing and store publishing, runs unit/widget/integration tests, and generates reproducible artifacts so teams catch regressions early and ship reliably. For learners and professionals working on JustAcademy real-time projects, Codemagic removes the overhead of maintaining CI infrastructure, speeds iteration, and provides a repeatable pipeline for demonstrating and delivering polished app releases.
Using Flutter's Hot UI (hot reload and hot restart) lets developers inject code changes into a running app and see updated layouts, styles and behaviours instantly without losing app state, making it ideal for rapid prototyping. This real-time feedback loop accelerates iteration on widgets, animations and responsive designs, improves collaboration between designers and engineers, and dramatically shortens the path from idea to working MVP.
In 2025, pairing Flutter with Supabase vs Firebase means choosing between an open‑source, Postgres‑first backend and a mature Google serverless platform: Supabase gives Flutter apps SQL‑centric workflows, real‑time subscriptions, row‑level security and lower vendor lock‑in with predictable costs and direct SQL access, while Firebase offers Firestore, Auth, Functions, Analytics, polished SDKs, global scaling and turnkey managed features (offline sync, analytics, A/B testing). Both speed cross‑platform development and real‑time experiences; pick Supabase for relational control and openness, or Firebase for convenience and a broader managed ecosystem.
In 2025, Flutter and NativeScript are both mature cross-platform frameworks with different strengths: Flutter (Dart) compiles to native code and provides a rich, cohesive widget-driven UI, excellent performance, and consistent look across mobile, web and desktop, making it ideal for visually complex apps and teams that want a single expressive UI layer; NativeScript (TypeScript/JavaScript) maps directly to native UI components and gives seamless access to platform APIs, appealing to teams with strong JS/TS skills who need native look-and-feel and tight platform integration—choose Flutter for unified UI control and performance, NativeScript for native parity and easier reuse of web/JS expertise.
Flutter CI/CD with GitHub Actions is a complete tutorial-style guide that shows how to automate building, testing, signing, and deploying Flutter apps using GitHub’s workflow runner; it covers creating YAML workflows to run platform-specific builds (Android/iOS), caching dependencies, running unit/widget/integration tests, managing secrets and code signing, generating artifacts, and releasing to stores or distribution channels. By following the tutorial, developers and JustAcademy learners can enforce consistent quality, catch regressions early, speed up delivery of real-time projects, and adopt industry-standard DevOps practices that make app releases reproducible and reliable.
AI-generated UI in Flutter uses machine learning to convert design files or natural-language prompts into responsive Dart widgets, automating layout, styling, accessibility and cross-platform tweaks so prototypes and production-ready screens can be produced far faster with fewer manual edits; this streamlines collaboration between designers and developers, lets teams focus on business logic and performance, and—as models and tooling improve—will become a core part of development workflows, accelerating app delivery and hands-on learning for learners and professionals at JustAcademy.
Optimizing network calls in Flutter with Dio means using Dio’s rich HTTP client features—centralized configuration and interceptors for headers, auth, logging and error handling; request cancellation, timeouts and concurrency control; retry strategies (exponential backoff); and response caching/compression—to reduce latency, save bandwidth and improve reliability. By encapsulating API logic in a configured Dio instance, applying retries and backoff, caching frequent responses, and handling errors consistently, apps become faster, more resilient and easier to maintain—especially important for real-time project work and production-ready certifications like those at JustAcademy.
JustAcademy’s "Deploy Flutter to Firebase: A Step-by-Step Tutorial" is a concise guide that walks you through preparing a Flutter app, configuring Firebase services (Authentication, Firestore, Hosting), and using the Firebase CLI to build and deploy your app—covering both web hosting and integration for Android/iOS where relevant. It explains creating a Firebase project, adding platform-specific Firebase SDKs, adjusting app settings, running production builds, initializing Firebase Hosting, and performing the final deploy, with tips for testing and automating releases via CI/CD. By following the tutorial, developers get a practical, end-to-end workflow to ship scalable, real-time Flutter apps quickly and reliably.
Flutter Desktop keyboard shortcuts let you define and handle platform-consistent key bindings (like Ctrl/Cmd combinations) to trigger app commands without a mouse. Using Flutter’s Shortcuts, Actions, and Intents APIs (or lower-level RawKeyboard events), you map logical key sets to intent objects and implement actions that run when those intents are invoked, while respecting focus and accessibility so shortcuts work predictably across Windows, macOS, and Linux.
