True/False Quiz Study App

I want to launch a lightweight study app aimed at recent high-school graduates (lulusan SMA). The core requirement is a clean True/False quiz module:

• Display one statement at a time, let the learner choose True or False, and immediately show whether the choice was correct.
• Pull questions from a simple, editable source (JSON, CSV, or an in-app list I can update later).
• Track total questions answered, correct answers, and percentage score at the end of each session.

A straightforward interface is fine—clear typography, large buttons, and a neutral colour palette. No sign-up screens or complex gamification for now; the focus is on getting the quiz flow solid.

Please deliver:
1. Complete, well-commented source code. I’m open to Flutter, React Native, or another cross-platform stack you’re comfortable with.
2. A brief README explaining how to build, run, and swap in new question sets.
3. An APK or test build link so I can try it on my Android phone.

If you have a small demo or past quiz project, feel free to share a link so I can see your style.
