defineBridgeAlias method

void defineBridgeAlias(String aliasName, String targetName)

GEN-078: Registers a class alias that maps aliasName to an existing bridged class registered under targetName.

This allows deprecated type alias names (e.g., MaterialStateProperty) to resolve to their canonical bridged class (e.g., WidgetStateProperty).

Implementation

void defineBridgeAlias(String aliasName, String targetName) {
  // Walk the scope chain to find the target bridged class
  BridgedClass? target;
  Environment? current = this;
  while (current != null) {
    target = current._bridgedClasses[targetName];
    if (target != null) break;
    current = current._enclosing;
  }
  if (target == null) {
    Logger.warn(
      "[Environment] Cannot register alias '$aliasName' -> '$targetName': "
      "target class not found",
    );
    return;
  }
  _bridgedClassesOrNew[aliasName] = target;
  Logger.debug(
    "[Environment] Defined bridge alias: $aliasName -> $targetName",
  );
}
