Feature flags (or feature toggles) allow you to enable/disable app features dynamically without redeploying code. This is useful for A/B testing, gradual rollouts, or quick fixes. Below, I’ll explain two approaches, with pros/cons, followed by code snippets in Spring Boot (backend) and Flutter (frontend). Approach 1: Unified Single Endpoint (Batch Fetch) Explanation: The backend exposes…
Feature Flags let you turn features on/off dynamically from the BackEnd, without redeploying your app. They’re perfect when you want features to depend on server load, user profile, A/B tests, or any other dynamic condition. Below is a clean mental model you can directly apply (Flutter, Java backend, etc.). ✅ What Feature Flags Solve Feature…
How Flutter handles images and asset density and scaling differently than Android’s legacy drawable-*dpi folders? Let’s break it down clearly 👇 🧩 1. How Flutter handles multiple resolutions Flutter doesn’t use the drawable-mdpi, drawable-hdpi, etc. system directly.Instead, it uses device pixel ratios (DPR) and asset variants. You can define image variants like this: And in…

You can have a horizontal scroll view (like a ListView or SingleChildScrollView with scrollDirection: Axis.horizontal) inside a vertical one — you just need to make sure Flutter knows how to size things properly so it doesn’t complain about unbounded height or conflicting scroll gestures. ✅ Example: Horizontal Scroll Inside Vertical Scroll ⚙️ Key Points…
Theming in Flutter is primarily implemented using the ThemeData class and the Theme widget, allowing you to define a consistent look and feel across your entire application. 🎨 Implementing Theming in Flutter Define ThemeData: Create one or more instances of the ThemeData class, typically for a light and a dark theme.
