Flutter Android WebView App

I need a developer who is comfortable in Flutter to create a simple Android-only application that displays several of my own custom web pages inside a clean, full-screen WebView. The goal is to publish a lightweight container app rather than rebuild those pages natively, so stable WebView handling, smooth navigation, and reliable loading states are essential.
You will receive the URLs (all hosted by me) and any brand assets; your task is to wire them up in Flutter, add basic back/forward controls, and make sure external links open in the device browser while internal links stay inside the app.

Deliverables
• Complete Flutter project with well-commented source
• Release-ready APK plus a debug build for testing
• Brief read-me explaining how to change the web page URLs and rebuild the app

I’m aiming for something maintainable that I can extend later, so clear structure and concise code matter more than extra features at this stage.
