Fix IllegalArgumentException

in Flutter

Solution

IllegalArgumentException in Flutter often arises from passing invalid arguments to platform-specific methods, commonly within plugins interacting with native code (like camera functionalities). Resolve it by carefully inspecting the arguments passed to the native functions, ensuring they adhere to the expected types and ranges specified in the plugin's documentation or native API documentation. If using hot restart, ensure to properly dispose of resources like camera controllers before the restart to avoid resource conflicts leading to invalid states.
