Example Usage #

Empty Dialog Example #

Although not a picker, per se, the showMaterialEmptyPicker helper displays the universal material design dialog wrapper that the pickers appear in. Using this directly, however, allows any content to be injected into the content area by passing in a custon Widget as the child. This code shows the basic structure of all the helpers:

showMaterialResponsiveDialog(
    context: context,
    child: Center(
        child: Container(
            padding: EdgeInsets.all(30.0),
            child: Text("Any content here."),
            style: TextStyle(
                fontSize: 20.0,
                fontStyle: FontStyle.italic,
            ),
        ),
    ),
);

Scroll Picker Example #

var selectedUsState = "Connecticut";

List<String> usStates = <String>[
  'Alabama',
  'Alaska',
  'Arizona',
  'Arkansas',
  'California',
  'Colorado',
  'Connecticut',
  ...
];

showMaterialScrollPicker(
    context: context,
    title: "Pick Your City",
    items: usStates,
    selectedItem: selectedUsState,
    onChanged: (value) => setState(() => selectedUsState = value),
);

Number Picker Example #

var age = 25;

showMaterialNumberPicker(
  context: context,
  title: "Pick Your Age",
  maxNumber: 100,
  minNumber: 14,
  selectedNumber: age,
  onChanged: (value) => setState(() => age = value),
);

Checkbox Picker Example #

List<String> iceCreamToppings = <String>[
  'Hot Fudge',
  'Sprinkles',
  'Caramel',
  'Oreos',
  ...
];
List<String> selectedIceCreamToppings = <String>[
  'Hot Fudge',
  'Sprinkles',
];

showMaterialCheckboxPicker(
  context: context,
  title: "Pick Your Toppings",
  items: iceCreamToppings,
  selectedItems: selectedIceCreamToppings,
  onChanged: (value) => setState(() => selectedIceCreamToppings = value),
);

Radio Picker Example #

var selectedUsState = "Connecticut";

List<String> usStates = <String>[
  'Alabama',
  'Alaska',
  'Arizona',
  'Arkansas',
  'California',
  'Colorado',
  'Connecticut',
  ...
];

showMaterialRadioPicker(
  context: context,
  title: "Pick Your City",
  items: model.usStates,
  selectedItem: selectedUsState,
  onChanged: (value) => setState(() => selectedUsState = value),
);

Selection Picker Example #

String speed = 'Ludicrous';

List<String> speedOptions = <String>[
  'Light',
  'Ridiculous',
  'Ludicrous',
  'Plaid',
];

List<Icon> speedIcons = <Icon>[
  Icon(Icons.sort),
  Icon(Icons.clear_all),
  Icon(Icons.swap_calls),
  Icon(Icons.select_all),
];

showMaterialSelectionPicker(
  context: context,
  title: "Starship Speed",
  items: speedOptions,
  selectedItem: speed,
  icons: speedIcons,
  onChanged: (value) => setState(() => speed = value),
);

Time Picker Example #

var time = TimeOfDay.now();

showMaterialTimePicker(
  context: context,
  selectedTime: time,
  onChanged: (value) => setState(() => time = value),
);

Date Picker Example #

var date = DateTime.now();

showMaterialDatePicker(
  context: context,
  selectedDate: date,
  onChanged: (value) => setState(() => date = value),
);

Color Picker Example #

Color color = Colors.red;

showMaterialColorPicker(
  context: context,
  selectedColor: color,
  onChanged: (value) => setState(() => color = value),
);

Palette Picker Example #

Color palette = Colors.green;

showMaterialPalettePicker(
  context: context,
  selectedColor: palette,
  onChanged: (value) => setState(() => palette = value),
);

Swatch Picker Example #

Color swatch = Colors.blue;

showMaterialSwatchPicker(
  context: context,
  selectedColor: swatch,
  onChanged: (value) => setState(() => swatch = value),
);

Theming #

It is highly recommended you use Flutter's built in theme styling with primarySwatch to automatically style all controls across your entire application.

ThemeData(
  primarySwatch: Colors.indigo,
)

If you desire to override the color for a given control, here is how to customize the theme:

var theme = ThemeData();
theme = theme.copyWith(
  primaryColor: Colors.green, // background color of the header area
  accentColor: Colors.black, // color of selected controls and button bar text
  dialogBackgroundColor: Colors.green[300], // background color of the entire dialog
  primaryTextTheme: theme.primaryTextTheme.copyWith(
    title: theme.primaryTextTheme.title.copyWith(
      color: Colors.lightGreen[50], // text color of the header area
    ),
  ),
  textTheme: theme.textTheme.copyWith(
    body1: theme.textTheme.body1.copyWith(
      color: Colors.green[900], // text color of dialog text
    ),
    button: theme.textTheme.button.copyWith(
      color: Colors.lightGreen[50], // text color of the action bar buttons
    ),
  ),
);

The example app demonstrates switching between light and dark themes globally.

However, if for some reason you want to change colors in an individual dialog, several parameters are exposed to allow this:

showMaterialResponsiveDialog(
    context: context,
    headerColor: Colors.green, // background color of the header area
    headerTextColor: Colors.white, // text fcolor of the header
    backgroundColor: Colors.lightGreen, // background color of the entire dialog
    buttonTextColor: Colors.red, // text color of the action bar buttons
    child: Text("Custom dialog colors"),
);

Customization #

You can customize the text that appears in various areas of the screen. The button labels automatically localize to the native language versions of "Ok" and "Cancel", unless replacement text is provided.

showMaterialNumberPicker(
  title: "Pick Your Age",
  confirmText: "Count me in",
  cancelText: "Negatory",
);

Sizing #

To prevent dialogs from growing to full screen on larger devices (or web) two properties control the maxmium size that it will grow:

  maxLongSide: 600,
  maxShortSide: 400,

The sides relate to if the dialog is showing in landscape or portrait mode. If you wish larger (or smaller) dialogs you can overide these values.
