How statistics are calculated
We count how many offers each candidate received and for what salary. For example, if a Flutter developer with SQLite with a salary of $4,500 received 10 offers, then we would count him 10 times. If there were no offers, then he would not get into the statistics either.
The graph column is the total number of offers. This is not the number of vacancies, but an indicator of the level of demand. The more offers there are, the more companies try to hire such a specialist. 5k+ includes candidates with salaries >= $5,000 and < $5,500.
Median Salary Expectation – the weighted average of the market offer in the selected specialization, that is, the most frequent job offers for the selected specialization received by candidates. We do not count accepted or rejected offers.

Flutter
So What Exactly Is Flutter?
Flutter is a solid mobile app development framework for developing cross-platform apps for different platforms such as iOS, Android, and Windows. It supports Google’s Dart programming language, and it comes with its own graphics library and material design for accelerating the development of apps and resulting in a more polished finished product.
The basic concept of Flutter is that widgets, and by combining different widgets developers can build a full user interface (UI). In other words, the widget is either a structural element (such as a button or a menu) or it’s a stylistic element (font or colour scheme). Flutter gives a developer predefined widgets, which look native.
Flutter comprises two essential components.
- Software development kit (SDK) – a set of tools that will help your developers compile code into native machine code (for iOS and Android).
- A framework or widgets-based UI library or set of UI components that the developer can use to customise and brand the application.
It is backed by Google, underpinned by Flutter itself, and used and trusted by global brands from eBay to Toyota. What’s more, it’s supported by Android Studio – a lightweight code editor and toolkit – and VS Code that does the same for Windows, Mac, and Linux. From the programmer’s point of view, everything is configurable.
To avoid performance issues, the platform compiles this Dart into the native code for each supported platform ahead of time, which improves application start-up time. Flutter is the only mobile SDK that supports a reactive view without JavaScript code, and that’s why so many apps were built using Flutter.
Cross-Platform Development
Flutter means you write the code once, and it will run everywhere: in iOS apps, and in Android apps, and, well, right now, production-level Windows apps too.
Cross-platform development, in other words, means you can code once and run anywhere, which is nothing but a boon for developers! Cross-platform frameworks have been around for quite some time now – but they have yet to deliver the same quality of apps for iOS and Android that Flutter seems to be delivering.
So, after all that, let me say that, while I have nothing against Flutter vs React Native or any other development framework … Most developers would say there is no competition when it comes to Flutter.
Faster Code Compilation
Flutter is fast – the Flutter code is interpreted to ARM or Intel machine code and JavaScript to run quickly on any device, and it has a handy feature called hot reload which means you can change the code and see the changes in real time. This is a great time-saver if you are busy designing an app, adding features or fixing bugs in your application’s code!
You can develop apps that will run on all the latest devices with Flutter in a small fraction of the time it would have taken you to develop them natively on both platforms. Or, if you have a low budget but need an app with more features, this is all possible, too, because cost-effectively delivering more with less was never really an option for native platform development teams because native apps are so complex to develop.
Great For Startups!
The platform is the best solution for start-ups who want to quickly develop a minimal viable product (MVP) and show it to investors or to the internal teams!
Moreover, Flutter is easy to pick up and use – much easier than say Java or React Native, by using something called widgets. They let you create a native-looking app without doing much coding. In exchange, you can use automated testing, developer tools and frameworks as needed to guide your workflow at every stage of building production-quality apps.

Where is SQLite used?
Embedded in Gadgets
- Got a smart toaster that burns time into your bread? Chances are SQLite is there, crunching numbers to make sure you don't end up with a charcoal snack.
Web Browser Dietician
- Ever wondered why your browser is a tab-hoarding monster yet doesn't crash? SQLite is the secret sauce, meticulously managing your bookmarks and history like a digital librarian on steroids.
Space Odyssey Companion
- Mission control needs their data, even in zero-gravity. SQLite is NASA's go-to buddy for data storage, proving it can handle the void of space without breaking a sweat.

- When your server decides to spill its guts in the log files, SQLite swoops in. It plays the role of therapist, sorting through the server's deepest thoughts and errors with ease.
SQLite Alternatives
PostgreSQL
Advanced open-source relational database with strong emphasis on concurrency, performance, standards compliance. Employed in web applications to large-scale data warehousing.
-- Connect to a database
\c database_name
-- Create a table
CREATE TABLE users (
id SERIAL PRIMARY KEY,
name TEXT NOT NULL
);
- Robust transaction and concurrency model
- Supports advanced data types and full-text search
- Can be overkill for small, lightweight applications
MySQL
Popular open-source relational database known for its reliability in web applications, provides a mix of high performance and ease of use, often used in combination with PHP.
-- Connect to a MySQL database
mysql -u username -p database_name
-- Create a table
CREATE TABLE users (
id INT AUTO_INCREMENT PRIMARY KEY,
name VARCHAR(100) NOT NULL
);
- Widely adopted with large community support
- Compatible with all major hosting providers
- Less optimal for complex transactions compared to other RDBMS
MongoDB
NoSQL database offering high scalability and flexibility with a document-oriented storage, JSON-like documents with schema. Ideal for rapid development and handling diverse data types.

db.users.insert({ name: "John Doe" });
- Schema-less structure allows for flexible data models
- Horizontal scaling suits large, distributed systems
- Not suited for ACID transaction-heavy applications
Quick Facts about SQLite
SQLite's Humble Beginnings on a Napkin Sketch
Back in the spring of '00, D. Richard Hipp had a eureka moment that didn't need a fancy lab – just a good ol' napkin! SQLite sprang from his brain onto that little square piece of paper. It was like he was doodling, but instead of a stickman, it was the first draft of a database that could nestle snugly into applications like a baby kangaroo.
Zero to SQL Hero with Self-Containment
This ain't your grandma's database! SQLite was the cool kid who didn't want to rely on anyone, so it came into this world in 2000 fully self-contained. With no server setup or configuration conundrums, it’s the database equivalent of a Swiss Army knife for software developers - it does it all, from storing data to tying virtual shoelaces.
-- Look ma, no installation needed!
SELECT 'Easy as pie!' AS SQLiteMotto;
Blasting Through Space-Time with Speed
With version 3 hitting the cyberspace shelves in 2004, SQLite didn't just upgrade; it broke the sound barrier with its new atomic commit feature. Imagine writing in your journal and, with a snap of your fingers, *poof* it's saved, safe from coffee spills and forgetful afternoons. That’s the kind of wizardry SQLite brought to the table that made databases nervously clutch their SQL statements.
-- Atomic commit in action:
BEGIN TRANSACTION;
INSERT INTO space_time (magic) VALUES ('🧙♂️');
COMMIT;
