I have an existing Flutter app that needs three things finished up so I can move it into production. First, the in-app WebView must load an external URL seamlessly on both iOS and Android. While doing so, it has to keep access to device features I expose from Flutter (for example camera, GPS or microphone calls that the webpage triggers). I have the base project ready; you wire up the WebView, pass the chosen feature channels to Java/Kotlin / Swift code and make sure permissions prompts behave natively. Second, a simple POST to my REST endpoint has to be triggered from the WebView or Flutter layer (whichever is cleaner). The payload and headers are already defined; you just need to implement the call, handle success/error and surface the result in the UI. Third, push notifications must be set up. I’m leaning on Firebase Cloud Messaging, but if you prefer OneSignal or another proven provider, let me know—what matters is that users receive foreground and background notifications, tapping them routes correctly, and tokens are stored securely for later use. Deliverables • WebView module that loads the external site and bridges selected device features • Robust API POST method with error handling and UI feedback • Fully working push-notification pipeline (Android & iOS), including token management and click-through routing • Clean, well-commented code plus a brief README on how to extend or maintain the setup If you have recent Flutter WebView and FCM work to show, that will help me pick fast. Looking forward to your questions or a quick turnaround proposal.

Hi, I'd love to help with your "Flutter WebView & Push Setup" project. I craft fast, pixel-perfect static sites and landing pages in clean HTML5/CSS3 with Bootstrap or Tailwind — fully responsive across mobile, tablet, and desktop. For a fixed project involving mobile app development, iphone, android, phonegap, kotlin, web development, flutter, rest api, I convert Figma/PSD/XD designs into crisp, semantic markup that matches the design exactly. I deliver lightweight, cross-browser-tested code with smooth load times. I'd be glad to discuss the details and timeline — when can we connect? Final timeline and cost will be confirmed in chat after a complete understanding and documentation of the project expectations in detail.

Hello, I can help you complete the remaining Flutter work and prepare the application for production on both iOS and Android. I have experience working with Flutter WebView integrations, native platform channels, REST APIs, and Firebase Cloud Messaging. I can seamlessly load your external URL within the WebView while exposing selected device capabilities (camera, GPS, microphone, etc.) through native Android (Java/Kotlin) and iOS (Swift) implementations with proper permission handling. The deliverables will include: * WebView integration with native feature bridging and permission management. * Secure REST API POST implementation with proper headers, error handling, and UI feedback. * Complete push notification setup using FCM (or OneSignal if preferred), including foreground/background notifications, token management, and notification click-through routing. * Clean, well-documented code along with a brief README for future maintenance and extensions. I will ensure the implementation follows Flutter best practices and is production-ready across both platforms. I'm available for a quick turnaround and would be happy to discuss any existing project structure or technical requirements before getting started. Best regards, Abhishek

Flutter WebView with native feature bridging means you need MethodChannels wired for every device access—the WebView itself won’t expose camera or GPS without custom handlers in Swift/Java/Kotlin for iOS/Android. I wired up this exact pattern for a client two months ago: external site as WebView, tapped device features, native permission dialogs, plus async (POST) calls back to a server. REST call is simple—Dio or http, result surfaced in an overlay widget. For push, I’d use FCM unless you already run OneSignal; background/foreground/message tap all handled. Is your main external site a single domain, or will you allow user-provided URLs in the WebView? Ready to start—send the repo. Pradeep

Hello, I understand you are looking to enhance your existing Flutter app by implementing a seamless in-app WebView that loads an external URL while maintaining access to device features like camera, GPS, and microphone calls. Additionally, you require a POST method to trigger a REST endpoint from either the WebView or Flutter layer, along with setting up push notifications using Firebase Cloud Messaging or another preferred provider. The main technical challenge is ensuring the seamless integration of the WebView with device features while handling permissions prompts natively. A common issue in systems like this is managing token storage securely for push notifications. To tackle this, I would focus on creating a robust WebView module that bridges device features, implementing a reliable API POST method, and setting up a fully functional push-notification pipeline for both Android and iOS. I have experience in developing similar systems with a focus on seamless integrations and reliable data handling. A few questions to better understand the scope: Q1- Do you have a preference for the provider for push notifications (Firebase Cloud Messaging, OneSignal, etc.)? Q2- Are there any specific UI requirements for displaying the push notifications? Happy to discuss the details and suggest the best technical approach. I can start immediately and work within your timeline. Best regards, Hoang Van Phi
