Discussing the cost of Flutter app development in 2024 involves understanding various factors. These factors influencing pricing can be the complexity of the app, the geographical location of the best Flutter app development company you are hiring, the experience level of developers, etc. Availing to the additional services can also influence the cost. These services can be UI/UX design, project management, and post-launch support. 

Prices can vary significantly based on these factors, here are some methodological insights and tentative calculations for different types of projects that can help. 

Factors Influencing Cost

• App Complexity: Basic apps (simple UI, minimal features) are cheaper than complex apps (advanced UI/UX, multiple features, backend development).
   
• Development Team's Location: Costs can vary by region, with developers in North America and Western Europe generally charging more than those in Eastern Europe, Asia, or Latin America.
   
• Experience Level: Senior developers and reputable companies charge more but can offer higher quality and faster delivery.Additional Services: Including design, testing, deployment, and maintenance services can increase the overall cost.

Tentative Calculations

• Basic App Development

A simple app with basic functionality, without backend development, might take 400-600 hours. Assuming an average rate of $50/hour (considering a mix of regions), the cost would range from $20,000 to $30,000.

• Mid-Level App Development

A more complex app with custom UI/UX design, a backend server, and standard features (e.g., social login, ecommerce functionality) could take 600-900 hours. With a slightly higher rate of $60/hour, the cost could range from $36,000 to $54,000.

• Complex App Development

High-end apps with advanced features (e.g., AI, complex animations, real-time functionalities) might take over 1000 hours of an expert Flutter application development company. At an average rate of $70/hour, the cost could exceed $70,000.

Real-World Case Studies

Here are some real-world case studies that provide a tentative insight into the cost of hiring Flutter development companies.

• Hamilton Musical: The official app for the Hamilton Musical was developed using Flutter. While specific development costs were not publicly disclosed, similar entertainment and media apps typically range from $50,000 to $100,000, depending on the features and content management requirements.
• Reflectly: An AI-based personal journal app built with Flutter, Reflectly likely had development costs in the mid to high range due to its use of artificial intelligence and sophisticated UI. Similar apps can cost between $40,000 and $80,000.
