Overview
source_helper is a Dart package developed by Google that provides utilities for generating Dart source code programmatically. It specializes in safely creating String literals from any String value, ensuring proper escaping and formatting. This is particularly useful in code generation scenarios where correctness and readability are critical. The package supports multiple platforms including Android, iOS, macOS, Windows, and Linux, making it ideal for cross-platform development workflows involving build-time code generation.
