/// A simple example demonstrating basic usage of the googleai_dart package.
///
/// This example shows how to:
/// - Initialize the Google AI client from environment variable
/// - Generate content using the Gemini API with convenience methods
/// - Handle the response using extension methods
///
/// To run this example:
/// 1. Get an API key from https://ai.google.dev/gemini-api/docs/api-key
/// 2. Set the environment variable: export GOOGLE_GENAI_API_KEY=your_key
/// 3. Run: dart run example/example.dart
