PHP2Shell (CVE-2026-109618 and CVE-2026-109619) went public with patches on October 21, 2026. Both are rated critical (CVSS 9.2), and an exploit attempt was recorded four days before the fix. A PHP server behind your app that runs 8.1 or earlier has no official patch. The back end gets upgraded or replaced, and a first Flutter build reaches testers in 7 days. Read our PHP2Shell explainer.
PHP to Flutter migration services turn an existing PHP web system into mobile apps for US businesses, built with Flutter, Google's UI toolkit. One Dart codebase produces iPhone and Android apps, and the same code can target the web if you want it.
Flutter covers the screens, and the server stays in charge of pricing, stock, bookings and accounts. The PHP side must now speak JSON to the app. Sound PHP code moves to PHP 8.4 with a proper REST API. Code that would not survive the change is rebuilt in a framework like Laravel.
Techno Mantra is an AI and web development company that builds AI applications, websites, SEO programs and custom CRM systems for businesses in the US, Canada and Australia. The price is fixed before work starts, and a first test build arrives within 7 days.
What Flutter brings to a PHP product
A single Dart codebase means one team, one test suite and one release cycle for both app stores.
Identical on every device
Flutter renders its own widgets, so your design matches on a new iPhone and an entry-level Android handset.
Fast to build and tweak
Hot reload shows code edits in seconds, so design changes can be reviewed during the call.
Smooth performance
Dart compiles ahead of time to ARM machine code, so catalogs, maps and dashboards scroll and animate without stutter.
Included in the Flutter project
- Review of your PHP code and the data the app must read and write
- PHP moved to patched PHP 8.4, or a new API in Laravel
- Token authentication between the app and the server
- Flutter app in Dart, built once for iOS and Android
- State management with Riverpod or Bloc, kept plain and documented
- Push notifications through Firebase Cloud Messaging
- Local storage for offline screens and saved drafts
- TestFlight and Google Play testing builds, then help with store listings
First week of your Flutter build
Day 1: Plan the API and app
Reading the PHP code settles keep or rebuild for the back end, then you approve the screen flow and a fixed price.
Days 2-4: Server, then widgets
JSON endpoints are built on PHP 8.4 or the new framework, and the main Flutter screens are wired to them.
Days 5-6: Real-phone testing
The app runs on a range of iOS and Android devices, bugs and slow spots get fixed, and your team receives test builds.
Day 7: Ship to testers
The patched API goes live, and the Flutter app reaches TestFlight and Play internal testing ahead of store submission.
Mobile browser vs Flutter app
What your customers notice when the PHP system gets a Flutter front end on their phones.
| PHP site in a mobile browser | Flutter app | |
|---|---|---|
| Look and feel | Depends on the browser and screen | Same branded design on every device |
| Speed | Full page loads over mobile data | Compiled app, only data travels |
| Alerts | None outside email | Push notifications via Firebase |
| Without signal | Blank page | Saved data and offline drafts |
| Backend | Old PHP rendering HTML | JSON API on PHP 8.4 or Laravel |
| Platforms | Web only | iOS, Android and optional web build |
Why trust us with your Flutter app
The team comes from the server side of PHP, so no app ships on top of a weak back end.
Server security first
Before release, the server moves to PHP 8.4.27 or is rebuilt, so the app never talks to an exposed back end.
A fixed price for the screens in scope, agreed before work starts.
NDA signed on request before you share code or product plans.
Flutter app projects for US firms
This service is for businesses in the United States that run on a PHP system and now want a branded mobile app. Calls overlap US Eastern hours, and feedback on each build gets a reply within one business day.
You get a project manager, a written plan, an NDA on request and delivery dates you can build a launch around. The team has 5,000+ projects and 3,460+ clients behind it.

Frequently asked questions
Straight answers about our PHP to Flutter Migration service.
Most small and medium projects have a secured back end and a first Flutter build with testers within 7 days. Large apps follow a phased plan, with the first part live inside those 7 days. Apple and Google set App Store and Play review times, which come on top.
Yes. Flutter talks to any server over HTTP and JSON. If your PHP code holds up, it moves to PHP 8.4.27, which carries the PHP2Shell fix, and gains the endpoints the app needs.
Pick Flutter for one custom design everywhere and rich animation. Pick React Native if your team already writes React for the web and wants to share code. The audit recommends one based on your plans.
Yes, and it works well for logged-in tools and dashboards. Public pages that need SEO are better kept on a normal website, because search engines read Flutter web pages poorly.
You do. The Flutter project, the back-end code and the store accounts are yours, handed over as repositories with setup notes.
Yes. Clients in the United States get calls that overlap US Eastern hours, a fixed price, an NDA on request and one contact who shares each build.
Is your PHP app still on an old version?
Send the URL or repository, under NDA if needed. The audit checks for the PHP2Shell flaw and outdated code and shows what a 7-day migration looks like.
