Mis muutus Dart 2.0-s automaatse tüüpide teisendamise osas ja miks sellest loobuti?

In Dart 2.0, automatic type conversions (implicit downcasts) were abandoned to improve type safety and performance. Previously, the compiler automatically performed type conversions, which could lead to runtime errors if types did not match.

Now, all type conversions must be explicit, allowing errors to be detected at compile time and making the code more predictable and reliable.

Example:

Object obj = "string";
String str = obj; // Compilation error in Dart 2.0
String str = obj as String; // Correct, explicit conversion

Thus, abandoning automatic conversions has improved code quality and type safety.
