Getting Started

  cuberto_bottom_bar: ^1.1.1+1


For now this is limited to more than 1 tab, and less than 5. So 2-4 tabs. textColor will only be applied in the case of STYLE_NORMAL, in case of STYLE_FADED_BACKGROUND the tabColor will be set as textColor,(if tabColor is not set inactiveColor will be set)

manually drawer or endDrawer has to be added and then respective drawer has to be added in CubertoBottomBar ( CubertoDrawer.NO_DRAWER for no drawer, CubertoDrawer.START_DRAWER for drawer and CubertoDrawer.END_DRAWER for endDrawer)

By default the drawer overlaps the CubertoBottomBar, for that margin: EdgeInsets.only(bottom: 60.0) has been added. (Please check with the example)

The values in onTabChangedListener: (position, title, color) (position, title and color are null at the beginning), but gets the value once the tab is clicked.

Basic Usage

Adding the widget

bottomNavigationBar: CubertoBottomBar(
        inactiveIconColor: inactiveColor,
        tabStyle: CubertoTabStyle.STYLE_FADED_BACKGROUND, // By default its CubertoTabStyle.STYLE_NORMAL
        selectedTab: currentPage, // By default its 0, Current page which is fetched when a tab is clickd, should be set here so as the change the tabs, and the same can be done if willing to programmatically change the tab.
        drawer: CubertoDrawer.NO_DRAWER, // By default its NO_DRAWER (Availble START_DRAWER and END_DRAWER as per where you want to how the drawer icon in Cuberto Bottom bar)

            .map((value) => TabData(
                iconData: value.icon,
                title: value.title,
                tabColor: value.color,
                tabGradient: value.gradient))
        onTabChangedListener: (position, title, color) {
          setState(() {
            currentPage = position;
            currentTitle = title;
            currentColor = color;

class Tabs {
  final IconData icon;
  final String title;
  final Color color;
  final Gradient gradient;

  Tabs(this.icon, this.title, this.color, this.gradient);

getGradient(Color color) {
  return LinearGradient(
      colors: [color.withOpacity(0.5), color.withOpacity(0.1)],
      stops: [0.0, 0.7]);

List<Tabs> tabs = new List();
tabs.add(Tabs(, "Search",, getGradient(;
tabs.add(Tabs(Icons.alarm, "Alarm", Colors.amber, getGradient(Colors.amber)));
tabs.add(Tabs(Icons.settings, "Settings", Colors.teal, getGradient(Colors.teal)));
