Frequently Asked Questions
Find in-depth answers to common questions and gain a deeper understanding of our Flutter development services.
Native Flutter apps are developed using languages like Kotlin or Java exclusively for Flutter devices, offering peak performance and full hardware access. Hybrid apps (using React Native or Flutter) share code across platforms while maintaining close-to-native performance, making them more cost-effective for multi-platform needs.
We typically support the latest 3-4 major Flutter versions to ensure compatibility with over 90% of active devices while leveraging modern features. We also conduct thorough backward compatibility testing to ensure smooth performance on older builds.
Security is built into our core development process. We implement end-to-end data encryption, secure API communication (HTTPS/SSL), ProGuard/DexGuard for code obfuscation, and follow Flutter's official security best practices to protect user data from vulnerabilities.
The timeline depends on the app's complexity. A simple MVP might take 8-12 weeks, while a comprehensive enterprise-grade application with complex integrations can take 4-6 months. We provide detailed project timelines after the initial discovery phase.
