The cost to make a Flutter app for your business can vary significantly depending on several factors:

1. App Complexity: More complex apps with advanced features, animations, integrations, etc. will generally cost more to develop than simpler, basic apps.
2. Developer Experience: Experienced Flutter developers will typically charge higher rates than less experienced developers.
3. Development Timeline: Faster turnaround times often come with higher costs, while longer timelines can provide cost savings.
4. Platform Support: Developing for both iOS and Android platforms will be more expensive than a single platform.
5. Post-Launch Maintenance: Ongoing app updates, bug fixes, and feature additions need to be factored into the overall budget.
