simple_aws_translate

A simple implementation of the AWS Translate plugin for Flutter. This plugin allows you to easily integrate AWS Translate services into your Flutter application.

DISCLAIMER: This is not the officially released AWS plugin.

⚠️ FOR TESTING PURPOSES ONLY ⚠️

DO NOT USE THIS PLUGIN IN PRODUCTION

CRITICAL SECURITY WARNING: This plugin requires you to embed AWS credentials (access key and secret key) directly in your application, which means:

1. YOUR AWS CREDENTIALS WILL BE EXPOSED in your application package
2. Anyone with access to your application can potentially extract your AWS credentials
3. This could lead to unauthorized use of your AWS services and SIGNIFICANT FINANCIAL COSTS
4. Your AWS account could be compromised, leading to security breaches

This plugin is STRICTLY FOR TESTING AND DEVELOPMENT ENVIRONMENTS ONLY. For production applications, you should:

• Use a secure backend service to handle AWS API calls
• Implement proper authentication mechanisms
• Consider using AWS Cognito or other secure authentication services
• Never embed AWS credentials in client-side code

By using this plugin, you acknowledge that you understand these risks and that you will only use it for testing purposes.

Features

• Simple API to translate text using AWS Translate
• Support for all AWS regions
• Improved error handling with detailed error messages
• Configurable source and target languages

Getting Started

Installation

Add this to your package's pubspec.yaml file:

dependencies:
  simple_aws_translate: ^0.0.7

Initialization

To use this plugin, call the init function with your AWS credentials. You should initialize the plugin only once, typically at app startup.

// Initialize with default region (Singapore)
SimpleAwsTranslate.instance.init(
  accessKey: "your_access_key",  // Store securely, do not hardcode
  secretKey: "your_secret_key"   // Store securely, do not hardcode
);

// Or specify a custom region
SimpleAwsTranslate.instance.init(
  accessKey: "your_access_key",
  secretKey: "your_secret_key",
  region: AwsRegion.usEast1  // Use US East (N. Virginia) region
);

Translating Text

After initialization, you can use the translateText method to translate text:

try {
  // Translate from auto-detected language to English
  String result = await SimpleAwsTranslate.instance.translateText(
    text: "Hallo bang!", 
    to: "en"
  );
  print("Translated result: $result");
  
  // Or specify the source language
  String result2 = await SimpleAwsTranslate.instance.translateText(
    text: "Hallo bang!",
    from: "id",  // Indonesian
    to: "en"     // English
  );
  print("Translated result: $result2");
  
} on AwsTranslationException catch (e) {
  print("Translation error: ${e.message}");
}

Available Regions

The plugin supports all AWS regions. You can specify the region during initialization:

SimpleAwsTranslate.instance.init(
  accessKey: "your_access_key",
  secretKey: "your_secret_key",
  region: AwsRegion.euWest1  // Europe (Ireland)
);

Available regions:

• AwsRegion.apNortheast1 - Asia Pacific (Tokyo)
• AwsRegion.apNortheast2 - Asia Pacific (Seoul)
• AwsRegion.apSouth1 - Asia Pacific (Mumbai)
• AwsRegion.apSoutheast1 - Asia Pacific (Singapore) [Default]
• AwsRegion.apSoutheast2 - Asia Pacific (Sydney)
• AwsRegion.caCentral1 - Canada (Central)
• AwsRegion.euCentral1 - Europe (Frankfurt)
• AwsRegion.euWest1 - Europe (Ireland)
• AwsRegion.euWest2 - Europe (London)
• AwsRegion.euWest3 - Europe (Paris)
• AwsRegion.saEast1 - South America (São Paulo)
• AwsRegion.usEast1 - US East (N. Virginia)
• AwsRegion.usEast2 - US East (Ohio)
• AwsRegion.usWest1 - US West (N. California)
• AwsRegion.usWest2 - US West (Oregon)

Error Handling

The plugin provides detailed error information through the AwsTranslationException class:

try {
  String result = await SimpleAwsTranslate.instance.translateText(
    text: "Hello world",
    to: "fr"
  );
  print("Translated result: $result");
} on AwsTranslationException catch (e) {
  print("Error code: ${e.code}");
  print("Error message: ${e.message}");
}

Testing and Development

For testing and development purposes only, you can create temporary AWS credentials with limited permissions. See the AWS documentation for more information on creating temporary security credentials.
