Introduction
A mortgage loan app is a mobile application that helps users calculate, compare, and apply for home loans directly from their smartphones. It is a loan-based cross-platform mobile application.
We are building a mortgage loan app in this project. This project is coded and designed using flutter framework. Instead of visiting banks, filling out paperwork, or waiting days for updates, users can manage the entire mortgage journey from their smartphone. These apps typically include loan calculators, EMI estimators, interest rate comparisons, eligibility checks, and secure document uploads. Users can instantly calculate how much they can borrow, explore different loan terms, and understand repayment obligations with clear visual breakdowns.
Modern mortgage apps also provide real-time application tracking, showing each stage of approval submission, verification, underwriting, and final decision. Many apps integrate identity verification, credit score checks, and personalized loan recommendations to streamline the process even further. This reduces delays, minimizes human error, and increases transparency. But in this app project, we are not doing anything professional. This is a beginner-level project that demonstrates the calculation of a loan based on interest. See the screenshots below.
Why use Flutter?
- Flutter lets you write one codebase for both iOS and Android.
- It compiles to native ARM code and uses its own rendering engine for consistent, high-performance UI across devices.
- Flutter’s widget system allows pixel-perfect, customizable design that adapts to your brand while maintaining platform norms.
- Maintenance happens once, and security updates, bug fixes, and feature rollouts apply across platforms at once.
- Flutter’s modular architecture makes scaling realistic and manageable.
- Flutter is backed by Google and supported by a large global developer community.
Building the project
The Flutter Mortgage Loan App is developed using Dart, a client-optimized programming language designed for fast and efficient app development across multiple platforms. Dart seamlessly integrates with Flutter’s widget-based architecture, making it ideal for building responsive and interactive mobile applications.
In this project, we leverage both stateful and stateless widgets to manage dynamic and static UI elements efficiently. The app also incorporates custom fonts, which are imported externally to enhance the visual appeal. Additionally, we have customized the app theme with new styles to create a unique and polished user interface.
For mathematical operations, the dart:math library is imported, enabling the use of essential mathematical functions within the app. Colors are overridden and customized, allowing us to define a consistent color palette that can be reused across the project.
Key UI elements used in this app include Row, Column, Container, Child, Children, Widget, ListView, Scaffold, Icons, and InkWell. These components work together to create a simple, clean, and user-friendly interface.
The Flutter Mortgage Loan App is fully functional and runs without errors. To test the application, you will need an emulator or a physical device. Download the app today and experience a seamless mortgage loan application process firsthand.
