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.

Release Version - 1.0.0
Initial release date - July 30, 2021

Deployment is not currently in use

• Flutter
• Dart
• Android Studio

Before you get started, follow these requirements

• Firebase project
• Google maps API
• Dart SDK >=2.14.0 <3.0.0
• Flutter SDK >=2.0.0

• Download or clone the repository
• Move the project to the selected directory
• Open it with a code editor (Android Studio, Visual Studio Code)
• Add firebase config file
  • iOS - GoogleService-Info.plist
  • Android - google-services.json
  • Web - Follow the instructions
• Run flutter clean and pub get commands
• Do not update / upgrade gradle and other versions until the app is up and running with built versions

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

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

Run this to check that everything is set up correctly:

flutter doctor -v flutter devices

Accept any Android licenses if prompted.

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 ..

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

ext.kotlin_version = '1.6.10'

flutter clean flutter pub get flutter run

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

**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.

List devices:

flutter devices

Run on a chosen device:

flutter run -d emulator-5554

Replace emulator-5554 with your device ID.
