>Solution :

What really happened is, you’re trying to use a value, which is null, but, the Text widget is expecting a string, rather than null. This is the root cause of your error.

You can fix the error by making sure your data is not null or you can use a null safe operator on your nullable data.

Example:

Text(userData['name'] ?? 'name not found')

Happy coding 😀
