## Summary

`InputDecoration.collapsed` invalid parameters `floatingLabelBehavior` and
`floatingLabelAlignment` are deprecated.

## Background

`InputDecoration.collapsed` constructor is used to
create a minimal decoration without a label.

The parameters `floatingLabelAlignment` and `floatingLabelBehavior` have
no effect because an input decoration created using
`InputDecoration.collapsed` has no label.

## Migration guide

To migrate, remove usage of `floatingLabelBehavior` and `floatingLabelAlignment`
parameters when calling the `InputDecoration.collapsed` constructor.
Those parameters had no effect.

Code before migration:

```dart
InputDecoration.collapsed(
  hintText: 'Hint',
  floatingLabelAlignment: FloatingLabelAlignment.center,
  floatingLabelBehavior: FloatingLabelBehavior.auto,
),
```

Code after migration:

```dart
InputDecoration.collapsed(
  hintText: 'Hint',
),
```

## Timeline

Landed in version: 3.24.0-0.1.pre<br>
