## Summary

The [`InputDecoration.maintainHintHeight`][] parameter was deprecated
in favor of the [`InputDecoration.maintainHintSize`][] parameter.

## Context

The default intrinsic size of an input decorator depends on the hint size.
The [`InputDecoration.maintainHintSize`][] parameter can be set to `false` to
make the intrinsic size ignores the hint size when the hint isn't visible.
Previously, the `InputDecoration.maintainHintHeight` parameter was
used to override the default intrinsic height and had no impact on the
intrinsic width.

## Description of change

The [`InputDecoration.maintainHintHeight`][] is deprecated in
favor of [`InputDecoration.maintainHintSize`][] which makes both the intrinsic
width and height depend on the hint dimensions.

## Migration guide

Replace [`InputDecoration.maintainHintHeight`][] with
[`InputDecoration.maintainHintSize`][] to override the default intrinsic size
computation.

Code before migration:

```dart highlightLines=3
TextField(
  indicator: InputDecoration(
    maintainHintHeight: false,
  ),
),
```

Code after migration:

```dart highlightLines=3
TextField(
  indicator: InputDecoration(
    maintainHintSize: false,
  ),
),
```
