Overview
// FLUTTER 3 · ANDROID & iOS · VERSION 1.0.0
Put your exchange
in every pocket.
The official mobile client for CryptoEx Lite. Spot & binary trading, escrowed P2P, a full multi-coin wallet, KYC, staking and tick-by-tick WebSocket prices — one Flutter 3 / Dart codebase, shipping to Android and iOS. Every screen reads and writes to your own server. Nothing is faked.
Built to pair with the CryptoEx Lite web platform — same accounts, same balances, same admin panel. Your users switch between browser and phone without noticing a seam.
▲ IMPORTANT · READ BEFORE YOU BUY
This is an add-on for CryptoEx Lite — not a standalone app.
The app has no backend of its own. It is a client that connects to a CryptoEx Lite installation for accounts, balances, orders, KYC, P2P and support. To run this app for your own users, you must own and install the CryptoEx Lite web platform, which is sold as a separate item.
Buying this item alone will get you a beautiful app that has nothing to talk to. Please purchase the platform first — or alongside this one.

Screenshots prove nothing. Install the actual APK on any Android phone — the demo build is pre-wired to our live server, so you can browse markets, place a spot order, walk a deposit flow, open a P2P trade and message support before you spend a cent. No install of your own needed just to evaluate it.
Android only (.apk) · Approve "install from unknown sources" when prompted · Register a free test account inside the app · Once you own the platform, point the same app at your own server from Profile → Server settings.

Why this beats a Flutter UI kit
| 01 | Real records, not dummy screens. Balances, orders, P2P trades, KYC submissions and tickets are rows in your database. There is no hard-coded JSON pretending to be an exchange. |
| 02 | Prices stream. They don't poll. A dedicated WebSocket market client pushes per-tick updates into the markets list, charts and order book. No timer loops, no stale numbers, no battery drain. |
| 03 | Connect without rebuilding. First launch opens a Server setup screen — paste your site URL and the API key from Admin → Settings → Mobile App, and it connects. The same binary works against staging, production, or a client's install. |
| 04 | Steered from your admin panel. Hide signup, drop the app into maintenance mode, or force an update by minimum version — all from the web admin, without publishing a new build to the stores. |
| 05 | Architecture you can actually extend. Feature-first folders, Provider state management, one typed Dio API client and 24 focused services. Colours, spacing and text styles live in a single theme layer — restyle the entire app from four files. |

Requirements
// REQUIREMENTS
Read this before purchasing. The first item is not optional — the app is a client and needs a server to talk to.
The CryptoEx Lite web platform is required.
Sold separately. It provides the database, admin panel, matching engine, WebSocket service and the mobile API this app consumes. Without it the app has nothing to connect to and will not function.
GET THE PLATFORM →| REQUIRED | A running CryptoEx Lite installation on your own domain, reachable over HTTPS, with its WebSocket service running — live prices, P2P updates and live chat all depend on it |
| REQUIRED | The Mobile App API key from your install, found at Admin → Settings → Mobile App — you paste it into the app on first launch, no rebuild needed |
| REQUIRED | Flutter SDK 3.9 or newer (Dart 3.9+), with Java 11 for the Android toolchain |
| REQUIRED | Android Studio with the Android SDK to produce APK / AAB builds — Windows, macOS or Linux all work |
| REQUIRED | A Mac with Xcode — only if you intend to build and ship the iOS version. The Android build needs no Mac. |
| REQUIRED | Your own Android signing keystore before you publish — the project ships configured for debug signing so it runs immediately out of the box |
| DEVICES | Android 6.0 (API 23) or newer on the user's phone |
| DEVICES | iOS 13.0 or newer on the user's iPhone |
| OPTIONAL | A Firebase project for push notifications — drop in your own google-services.json and GoogleService-Info.plist. The app runs fine without it; you simply get no push. |
| OPTIONAL | Google Cloud OAuth clients for Google Sign-In — email and password login works out of the box without them |
| OPTIONAL | Google Play and Apple Developer accounts — needed only to publish to the public stores, not to build or distribute the app yourself |
No coding is required to connect the app. You do not edit any Dart file to point it at your server — enter your site URL and API key on the first-launch setup screen, and the same build works against staging, production, or a client's install.
Instructions
// INSTRUCTIONS
From a fresh copy of the source to a signed build pointed at your own exchange. Steps 1 to 4 are all you need to see the app running against your server; the rest is branding and release work.
Before you start: the CryptoEx Lite web platform must already be installed and running on your domain. It is sold separately and this app cannot work without it.
| 01 |
Install the CryptoEx Lite platform Get your exchange live on your own domain first, served over HTTPS, with its WebSocket service running. Confirm you can log in to the web admin panel before touching the app. |
| 02 |
Copy your Mobile App API key In the web admin, open Settings → Mobile App. Copy the API key shown there. The same page is where you later control signup visibility, maintenance mode and the minimum app version. |
| 03 |
Install Flutter and fetch the packages Install Flutter 3.9 or newer, unzip the source, then from the project folder run: flutter --version
flutter pub get flutter doctor |
| 04 |
Point the app at your server Open lib/core/config/app_config.dart and replace the connection defaults with your own domain and the API key from step 2: static const String defaultApiUrl = 'https://your-exchange.com';
static const String defaultApiKey = 'your-mobile-app-api-key'; static const String defaultWsUrl = ''; Leave defaultWsUrl empty unless your setup needs an override — the app takes the live WebSocket address from your admin panel, and otherwise derives it from your domain. You can also change the server at any time from inside the app, without rebuilding: Profile → Server settings, enter the URL and key, and tap Connect. Setting defaultApiUrl to an empty string makes the app open that setup screen on first launch instead. |
| 05 |
Run it Connect a device or start an emulator, then launch. You should reach the login screen of your own exchange and be able to sign in with a real account from your site. flutter run
|
| 06 |
Rename the app to your brand Set the display name in android/app/src/main/AndroidManifest.xml (the android:label attribute) and in ios/Runner/Info.plist. Change the package identifier in android/app/build.gradle.kts (both applicationId and namespace) and the bundle identifier in Xcode. Replace the launcher icons under android/app/src/main/res/mipmap-* and ios/Runner/Assets.xcassets/AppIcon.appiconset. |
| 07 |
Enable push notifications — optional Create a Firebase project, register your Android and iOS package identifiers, and replace android/app/google-services.json and the iOS GoogleService-Info.plist with your own. Skip this and the app still runs — you simply receive no push notifications. |
| 08 |
Enable Google Sign-In — optional Create OAuth client IDs in Google Cloud for Web and Android (plus iOS if you ship there), using your app's package name and signing certificate fingerprint, then enable Google login in your web admin. Email and password sign-in works without any of this. |
| 09 |
Build for release Create your own Android signing keystore and wire it into the release build type first — the project ships signed with debug keys so it runs immediately out of the box. Then: flutter clean
flutter pub get flutter build apk --release flutter build appbundle --release flutter build ipa --release |
| 10 |
Keep your version numbers in step On every release, bump version in pubspec.yaml and appVersion in lib/core/config/app_config.dart together. Your admin panel compares that value against its minimum version setting to show users the update screen, so an out-of-date constant will prompt people who are already current. |
