Height of TextField decreases when using OutlineInputBorder and label

[lisaerikssonw]

Steps to reproduce

1. Run the provided code example using border type UnderlineInputBorder as enabledBorder. Notice that the height adapts to the height of the SizedBox.
2. Change the border type from UnderlineInputBorder to OutlineInputBorder, and the height will decrease.
3. Note: this only seems to be reproducable if the TextField has a label. When removing the label, the height doesn't change when switching border types.

Only tested on Linux desktop.

Expected results

When changing the enabledBorder of InputDecoration from UnderlineInputBorder to OutlineInputBorder, I expect the height of the TextField to stay the same (200).

Actual results

The height decreases when changing from UnderlineInputBorder to OutlineInputBorder.

Code sample

Code sample

```dart void main() { runApp(const MyApp()); } class MyApp extends StatelessWidget { const MyApp({super.key}); @override Widget build(BuildContext context) { return MaterialApp( title: 'Flutter Demo', theme: ThemeData( colorScheme: ColorScheme.fromSeed(seedColor: Colors.deepPurple), useMaterial3: true, ), home: const MyHomePage(), ); } } class MyHomePage extends StatelessWidget { const MyHomePage({super.key}); @override Widget build(BuildContext context) { return const Scaffold( body: Center( child: SizedBox( width: 300, height: 200, child: TextField( decoration: InputDecoration( fillColor: Color.fromARGB(255, 142, 163, 118), filled: true, label: Text('Label'), enabledBorder: OutlineInputBorder( borderSide: BorderSide( color: Color.fromARGB(255, 79, 92, 64), ), ), contentPadding: EdgeInsets.symmetric(vertical: 20, horizontal: 10), ), ), ), ), ); } } ```

Hi @lisaerikssonw Can you provide the actual height you observed?

I checked this on Linux (Ubuntu distro), Android and macOS apps but the height stays 200 as expected (inspect height via Flutter Devtools)

Hello, The height of the SizedBox doesn't change, but the _BorderContainer>CustomPaint>renderObject>size of the Textfield changes from Size(300.0, 72.0) to Size(300.0, 56.0) when I switch between the different border types.

OutlineInputBorder:

UnderlineInputBorder:

Thanks for making it more evident. Observed the similar result as above on macOS and Android app targets and on Flutter master channel 3.27.0-1.0.pre.511.
