tabbed_view

Flutter widget inspired by the classic Desktop-style tab component. Supports customizable themes.

The TabbedView renders the presentation of the model.

The TabbedViewModel stores the tab data as name, content, buttons or any dynamic value.

Get started

The default theme is TabbedViewTheme.light().

    List<TabData> tabs = [];
    for (var i = 1; i < 7; i++) {
      tabs.add(
          TabData(text: 'Tab $i', content: Center(child: Text('Content $i'))));
    }
    TabbedWiew tabbedView = TabbedWiew(model: TabbedWiewModel(tabs));

Content builder

It allows creating the contents of the tab dynamically during the selection event.

    List<TabData> tabs = [];
    for (var i = 1; i < 5; i++) {
      tabs.add(TabData(text: 'Tab $i'));
    }

    TabbedWiew tabbedView = TabbedWiew(
        model: TabbedWiewModel(tabs),
        contentBuilder: (BuildContext context, int tabIndex) {
          int i = tabIndex + 1;
          return Center(child: Text('Content $i'));
        });

Tab

Extra button

    TabData tab = TabData(text: 'Tab', buttons: [
      TabButton(icon: Icons.star, onPressed: () => print('Hello!'))
    ]);
    TabbedWiew tabbedView = TabbedWiew(model: TabbedWiewModel([tab]));

Removing the close button

    var tabs = [
      TabData(text: 'Tab'),
      TabData(text: 'Non-closable tab', closable: false)
    ];
    TabbedWiew tabbedView = TabbedWiew(model: TabbedWiewModel(tabs));

Themes

Tabs area

Color

• The default TabsAreaTheme color is null.

    var tabs = [TabData(text: 'Tab 1'), TabData(text: 'Tab 2')];

    TabbedViewTheme theme = TabbedViewTheme.minimalist();
    theme.tabsArea.color = Colors.green[100];

    TabbedWiew tabbedView =
        TabbedWiew(model: TabbedWiewModel(tabs), theme: theme);

Tab gaps

• Gap before the tabs (allows negative value).
• Gap between tabs (allows negative value).
• Minimum gap after tabs. Separates the last tab and the buttons area.

    TabbedViewTheme theme = TabbedViewTheme.light();

    theme.tabsArea
      ..initialGap = 20
      ..middleGap = 5
      ..minimalFinalGap = 5;

    TabbedWiew tabbedView = TabbedWiew(model: model, theme: theme);

Predefined themes

Dark theme

    TabbedWiew tabbedView =
        TabbedWiew(model: model, theme: TabbedViewTheme.dark());

Mobile theme

    TabbedWiew tabbedView =
        TabbedWiew(model: model, theme: TabbedViewTheme.mobile());

Creating new theme

It is possible to create an entire theme from scratch.

    var tabs = [
      TabData(text: 'Tab 1'),
      TabData(text: 'Tab 2'),
      TabData(text: 'Tab 3')
    ];

    TabbedViewTheme theme = TabbedViewTheme();
    theme.tabsArea
      ..border = Border(bottom: BorderSide(color: Colors.green[700]!, width: 3))
      ..middleGap = 6;

    Radius radius = Radius.circular(10.0);
    BorderRadiusGeometry? borderRadius =
        BorderRadius.only(topLeft: radius, topRight: radius);

    theme.tabsArea.tab
      ..padding = EdgeInsets.fromLTRB(10, 4, 10, 4)
      ..buttonsOffset = 8
      ..decoration = BoxDecoration(
          shape: BoxShape.rectangle,
          color: Colors.green[100],
          borderRadius: borderRadius)
      ..selectedStatus.decoration =
          BoxDecoration(color: Colors.green[200], borderRadius: borderRadius)
      ..highlightedStatus.decoration =
          BoxDecoration(color: Colors.green[50], borderRadius: borderRadius);

    TabbedWiew tabbedView =
        TabbedWiew(model: TabbedWiewModel(tabs), theme: theme);
