New BasicTextField (BasicTextField2) limit maxLength

Question

How can I set a character limit in a BasicTextField (or BasicTextField2) in Jetpack Compose?

With the new BasicTextField function, which uses a state: TextFieldState as a parameter, it is no longer possible to directly intercept the text using text and onTextChange as before. This makes implementing a character limit more challenging since the internal state cannot be directly modified.

Is there an efficient way to implement this functionality with the new API?

There is the InputTransformation api for that, with a built-in maxLength transformation.

BasicTextField(
    inputTransformation = InputTransformation.maxLength(10),
)
