Remove invalid parameters for `InputDecoration.collapsed`

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',
),
