Thanks for the feedback!

As you said, the post has exactly provided you with technology recommendations and cost estimations.

Yes, Flutter can be a great choice for cross-platform app development and developers are widely using this framework for app development. React Native is just the suggestion, but it doesn’t mean that other frameworks are weak in comparison. Among all frameworks, React Native is one of the most popular choices but nothing can beat the simplicity of Flutter.

Further, whether it be outsourcing app development company or in-house app developers, support, and maintenance of the app is always provided but at a certain cost.

Moreover, reputed app development companies provide 30 days of free support to the app owners after the launch of the app! But on the other hand, availability of the in-house team will cause you a specific cost.
