Maybe next year I'll make a change
You wake up sore.
Not just your body, your mind.
Another long day⦠and still no progress.
You keep saying, βNext year Iβll change.β
But the truth is the longer you wait, the harder it gets.
Not because you canβt but because you get used to being uncomfortable.
Most people think changing careers in your late 20s or 30s is a setback.
Itβs not. Itβs a launchpad.
You bring something others donβt:
π₯ Real work ethic
πͺ Real resilience
π§ Real-world experience
The hardest part isnβt learning to code,
Itβs believing youβre worth the change.
Stop waiting for permission.
Your current situation isnβt permanent, itβs just temporary.
At @FlutterBegin, weβll guide you step-by-step.
The question isnβt whether you can afford to change.
Itβs whether you can afford not to.

Artificial intelligence doesn't make us dumber, it makes us smarter. It presents us with the challenge of asking the right questions. Artificial intelligence doesn't know what we want and that's why it's so incredibly important to develop a specific question for a specific request and that's often harder than you think.
You have to think carefully about what you need to ask the right question that is specific and then use the answer provided by artificial intelligence to solve your problem. This requires a lot of thought, and artificial intelligence helps us to formulate our concerns more precisely and apply the outputs specifically. Using artificial intelligence well and correctly is not a trivial task, but requires some effort.

Flutter Interview Q&A β Part 1 π±π‘
1οΈβ£ What is Flutter?
Answer: Flutter is Googleβs open-source UI toolkit for building natively compiled apps for mobile, web, and desktop β all from a single codebase.
2οΈβ£ What language is used in Flutter?
Answer: Flutter uses Dart, a modern object-oriented language optimized for UI, fast performance, and reactive programming.
3οΈβ£ What are widgets in Flutter?
Answer: Widgets are the building blocks of Flutter apps β everything from layout to text and buttons is a widget. They define both structure and behavior.
4οΈβ£ What is the difference between Stateless and Stateful widgets?
Answer:
StatelessWidget: The UI doesnβt change once built.
StatefulWidget: The UI can change dynamically during runtime using state.
5οΈβ£ What is the Widget Tree?
Answer: The Widget Tree represents the hierarchy of widgets in an app β it shows how widgets are nested and combined to form the UI.
6οΈβ£ What is setState()?
Answer: setState() notifies Flutter that the widgetβs state has changed, prompting the framework to rebuild the UI with updated data.
7οΈβ£ What is hot reload?
Answer: Hot reload allows you to instantly see code changes without losing the current app state β boosting productivity during development.
8οΈβ£ What is BuildContext?
Answer: BuildContext gives access to the widget tree location and allows interaction with inherited widgets and navigation.
9οΈβ£ What is the difference between mainAxisAlignment and crossAxisAlignment?
Answer:
mainAxisAlignment: Aligns children along the main axis (horizontal for Row, vertical for Column).
crossAxisAlignment: Aligns children across the perpendicular axis.
π Why use Flutter?
Answer: Flutter enables fast development, expressive UIs, and native performance on multiple platforms all from one codebase.

1οΈβ£ What is a layout widget in Flutter?
Answer: Layout widgets help you position, align, and size other widgets. Examples: Row, Column, Stack, Expanded, and Container.
2οΈβ£ What is the difference between Row and Column?
Answer:
Row: Aligns children horizontally.
Column: Aligns children vertically.
3οΈβ£ What is a Scaffold widget?
Answer: Scaffold provides the basic structure for a screen β including AppBar, Drawer, BottomNavigationBar, and FloatingActionButton.
4οΈβ£ What is Navigator in Flutter?
Answer: Navigator manages routes (screens) in Flutter. It allows navigation between pages using methods like push() and pop().
5οΈβ£ What is a route?
Answer: A route is simply a screen or page in a Flutter app. You can define routes using MaterialPageRoute or a named route map.
6οΈβ£ What is setState() vs Provider / Riverpod / Bloc?
Answer:
setState: Simple local state management.
Provider / Riverpod / Bloc: Used for managing global or complex state across multiple widgets.
7οΈβ£ What is InheritedWidget?
Answer: Itβs the base class for sharing data down the widget tree. Many state management solutions (like Provider) are built on it.
8οΈβ£ What is FutureBuilder?
Answer: FutureBuilder builds its UI based on the state of a Future (pending, completed, error) β useful for async data like APIs.
9οΈβ£ What is StreamBuilder?
Answer: StreamBuilder listens to a Stream and rebuilds its UI every time new data is emitted β perfect for real-time updates.
π What is the difference between Hot Reload and Hot Restart?
Answer:
Hot Reload: Updates code instantly while keeping app state.
Hot Restart: Restarts the app and resets all state variables.

Flutter Interview Q&A β Part 3 βοΈ
1οΈβ£ What is a Future in Flutter?
Answer: A Future represents a value that will be available later, often used for async operations like API calls or reading from a database.
2οΈβ£ What is async and await?
Answer:
async marks a function as asynchronous.
await pauses the function until the Future completes.
Example:
3οΈβ£ What is the difference between Future and Stream?
Answer:
Future: Returns a single value once.
Stream: Returns multiple values over time.
4οΈβ£ How can you improve performance in Flutter apps?
Answer:
β Use const widgets whenever possible.
β Avoid rebuilding large widget trees unnecessarily.
β Use ListView.builder instead of ListView for long lists.
β Cache images and network data.
β Minimize state changes.
5οΈβ£ What is the use of Keys in Flutter?
Answer: Keys help Flutter identify and preserve widget states when the widget tree changes β useful in lists and complex UIs.
6οΈβ£ What is the build() method?
Answer: Itβs the core method where you describe how your widget should look based on its current state.
7οΈβ£ When should you use StatelessWidget vs StatefulWidget?
Answer:
StatelessWidget: For UI that doesnβt change.
StatefulWidget: For UI that updates dynamically.
8οΈβ£ What are RepaintBoundary widgets?
Answer: These widgets isolate parts of the UI to avoid unnecessary repaints, improving rendering performance.
9οΈβ£ What is the use of const keyword in Flutter?
Answer: It makes widgets immutable and prevents them from rebuilding β boosting performance.
π What is widget tree, element tree, and render tree?
Answer:
Widget tree: Blueprint of UI.
Element tree: Holds widget instances.
Render tree: Handles actual layout and painting.
