title: How can I configure auto-capitalization behavior in Flutter's text entry fields?
body: <p>I'm experimenting with Flutter development on Windows.  I have a simple test app with an InputField.  I would like the first keyboard entry to be a capital letter but can't see a way of achieving that (e.g. launching the keyboard with shift pressed) that at the moment.  Any ideas?</p>
  <p>Code (a bit simplified) is:</p>
  <pre><code>import 'package:flutter/material.dart';
  
  void main() {
    runApp(new MaterialApp(
        theme: new ThemeData.dark(),
        home: new MainScreen()
    ));
  }
  
  class MainScreen extends StatelessWidget {
    @override
    Widget build(BuildContext context) {
      return new Scaffold(
          appBar: new AppBar(
              leading: new IconButton(
                  icon: new Icon(Icons.menu),
                  tooltip: 'Navigation menu',
                  onPressed: null,
              ),
              title: new Text('Test'),
          ),
          body: new NewTest(),
      );
    }
  }
  
  /// Widget
  class NewTest extends StatefulWidget {
    @override
    _NewTestInputState createState() =&gt; new _NewTestInputState();
  }
  /// State
  class _NewTestInputState extends State&lt;NewTest&gt; {
    InputValue _currentInput;
  
    void _handleInputChange(InputValue input) {
      if (input != _currentInput){
        setState(() {
          _currentInput = input;
        });
      }
    }
  
    void _handleInputSubmitted(InputValue input) {
      setState(() {
        _currentInput = const InputValue();
      });
    }
  
    @override
    Widget build(BuildContext context) {
      InputField _widget = new InputField(
          value: _currentInput,
          hintText: 'Enter text',
          keyboardType: TextInputType.text,
          autofocus: true,
          onChanged: _handleInputChange,
          onSubmitted: _handleInputSubmitted,
          style: new TextStyle(fontSize: 20.0),
      );
      Container _container = new Container(
          child: _widget,
          decoration: new BoxDecoration(
              border: new Border.all(
                  color: Colors.green[300],
                  width: 2.0,
              ),
          ),
          padding: new EdgeInsets.all(16.0),
      );
      return _container;
    }
  }
  </code></pre>
