What are the main differences between Dart and Crystal?
Dart and Crystal differ in syntax, type system, standard libraries, and common idioms, so copying code line for line usually will not compile. The converter maps each Dart construct to its closest Crystal equivalent. See the comparison table below for the key differences between Dart and Crystal.
Is the converted Crystal code accurate?
The AI produces high-quality Crystal code that preserves the behavior of your original Dart code and follows Crystal conventions. It handles common patterns, data structures, and idioms for both Dart and Crystal. For large or performance-critical code, review and test the Crystal output before using it in production.
Can I convert an entire Dart project to Crystal?
You can convert Dart files one at a time by pasting each file's code. For a full migration, convert each file and then review how classes, dependencies, and project structure map from Dart to Crystal. Signing in for free raises the input limit to 25,000 characters per conversion for larger files.
