Q: Trasparent background CurvedNavigationBar how it's possible do transparent background for CurvedNavigationBar?

This is the code about CurvedNavigationBar :
bottomNavigationBar: CurvedNavigationBar(
        onTap: (int index) => setState(() => _currentIndex = index),
        index: _currentIndex,
        buttonBackgroundColor: SVConst.mainColor,
        backgroundColor: Colors.transparent,
        color: SVConst.mainColor,
        items: <Widget>[
          for (final tabItem in TabNavigationItem.items) tabItem.icon
        ],
      ),

Thanks.

A: This is a common request from many flutter developers, but the plugin still has no support for this. But there is an indirect way to achieve it through Stack like this:
Scaffold(
    body: Stack(
      children: <Widget>[

        //Place your scaffold body here
        Text('This is the body'),

        Align(
            alignment: Alignment.bottomCenter,
            child: CurvedNavigationBar(
             onTap: (int index) => setState(() => _currentIndex = index),
             index: _currentIndex,
             buttonBackgroundColor: SVConst.mainColor,
             backgroundColor: Colors.transparent,
             color: SVConst.mainColor,
             items: <Widget>[
              for (final tabItem in TabNavigationItem.items) tabItem.icon
             ],
          ),
        ),
      ],
    ),
  );


A: Use this in Scaffold
extendBody: true,

and use this in CurvedNavigationBar
backgroundColor: Colors.transparent,

Here is the example
return Scaffold(
  ...
  extendBody: true,

  bottomNavigationBar: CurvedNavigationBar(
    backgroundColor: Colors.transparent,
    ...
  ),


A: This package is a good alternative.
