TrashPick Mobile App

✨ About

The TrashPick mobile app is designed to guide people on how to properly dispose of waste. Users can register as a Trash Picker or Trash Collector. Trash Pickers can post details about trash disposal and they can sell their trash to Trash Pickers. Trash Collectors can buy it from Trash Pickers and sell it to recycling centers. Both users have a chance to earn points and win rewards by using this app. This alpha release does not include the complete requirements and interface. This project has been developed as an open source for educational purposes.

🚀 Flutter Android Setup

Prerequisites Installation

1. Flutter SDK

Download and extract the Flutter SDK for Windows to a location like C:\flutter\flutter_windows_2.10.0-stable, then add it to your PATH:

$env:PATH = "C:\flutter\flutter_windows_2.10.0-stable\flutter\bin;" + $env:PATH
flutter --version

2. Java JDK 11

Install Java JDK 11 (not just JRE) and set the environment variables:

$env:JAVA_HOME = "C:\Program Files\Java\jdk-11.0.x"
$env:PATH = "$env:JAVA_HOME\bin;" + $env:PATH
java --version

3. Verify Your Environment

Run this to check that everything is set up correctly:

flutter doctor -v
flutter devices

Accept any Android licenses if prompted.

Project Configuration

Update Gradle

Edit android/gradle/wrapper/gradle-wrapper.properties and update:

distributionUrl=https\://services.gradle.org/distributions/gradle-7.6.1-all.zip

Update the Gradle wrapper by running:

cd android
./gradlew wrapper --gradle-version 7.6.1
cd ..

Update Kotlin (if needed)

If you encounter Kotlin errors, ensure android/build.gradle has:

ext.kotlin_version = '1.6.10'

Run Your App

flutter clean
flutter pub get
flutter run

To target a specific device: flutter run -d <device-id>

Troubleshooting

**Gradle/Java Incompatibility Issues:

If you see errors about Gradle↔Java incompatibility (like “Unsupported class file major version…”), then:

• Ensure Gradle wrapper is updated to 7.6.1
• Ensure JAVA_HOME points to Java 11
• If needed, add this to android/gradle.properties:

org.gradle.java.home=C:\\Program Files\\Java\\jdk-11.0.x

This forces Gradle to use the correct JDK.

8) Run on a Specific Device

List devices:

flutter devices

Run on a chosen device:

flutter run -d emulator-5554

Replace emulator-5554 with your device ID.
