Icon Without Label

Since these kind of icons require us to utilize custom widgets thus we will be using customItem widget for getting through it. It has two properties namely widget and selectedWidget.

Property	Type	Description
widget	widget	Used for inactive item.
selectedWidget	widget	Used for active item.
page	screen	Used for naming the screen to which we navigate once clicked upon item

We will utilize these two to achieve two different states for an icon active and inactive. Let us see the code example

Example


ViewGroup:
  BottomNavBar:
    styles:
      backgroundColor: white
      color: 0xFF9DAEC1
      selectedColor: black
      floatingBackgroundColor: 0xFF8A1C9D
      floatingIconColor: white
      notchColor: 0xFF0F0E1C
    items:
      - customItem:
          widget:
            IconWidget:
              inputs:
                icon: home
          selectedWidget:
            ActiveIconWidget:
              inputs:
                icon: home
        page: Home
 
      - customItem:
          widget: IconOnlyWidget
          selectedWidget: ActiveIconOnlyWidget
        page: Chat
 
      - customItem:
          widget:
            IconWidget:
              inputs:
                icon: account_balance_wallet
          selectedWidget:
            ActiveIconWidget:
              inputs:
                icon: account_balance_wallet
        page: Home

Output

Note:BottomNavBar is used to navigate across whole application so it always has a separate screen where it comes under [View Group]() with all the items corresponding to each screen of your application.

Explanation

Each item has two properties for active and inactive widget. IconWidget and IconOnlyWidget represents the in-active state / screen while ActiveIconWidget and ActiveIconOnlyWidget for active state / screen. Both of these are custom widgets. Its important to notice that IconWidget and ActiveIconWidget accept input as well which is the name of the icon we want to use.
