getConversionService method

Retrieves the currently assigned ConversionService.

This method provides access to the type conversion infrastructure for manual conversion operations when dependency injection is not available or suitable.

Usage Contexts:

• Configuration property resolution
• Data binding in web controllers
• Custom deserialization logic
• Format parsing and validation

Example:

class ConfigurationParser {
  final ConversionService conversionService;
  
  ConfigurationParser(this.conversionService);
  
  T parseConfiguration<T>(String key, String value) {
    return conversionService.convert<String, T>(value);
  }
}

// Manual usage
final service = context.getConversionService();
final timeout = service.convert<String, int>("30");
final ratio = service.convert<String, double>("0.85");
final enabled = service.convert<String, bool>("true");
final date = service.convert<String, DateTime>("2023-12-25");

print("Parsed values: $timeout, $ratio, $enabled, $date");
