body: <p>I have this <a href="https://i.stack.imgur.com/lksOt.png" rel="nofollow noreferrer">AppBarWidget </a> and I need to change the arrow back logo to my custom svg icon. I'm new in flutter and I can't find how to change it.</p>
  <p>Here is code for AppBar</p>
  <pre><code>    return AppBar(
        elevation: 0,
        backgroundColor: white,
        foregroundColor: black,
        shadowColor: Colors.transparent,
        toolbarHeight: 80,
        titleTextStyle: getCustomeStyle(
            fontSize: 25, fontWeight: FontWeight.w700, color: black),
        title: FittedBox(
            fit: BoxFit.fill,
            child: SizedBox(
              width: _width,
              child: Row(
                mainAxisAlignment: MainAxisAlignment.spaceBetween,
                children: [
                  Text(title),                
                    SvgPicture.asset(&quot;assets/images//logo/ShopIO.svg&quot;,
                        semanticsLabel: &quot;ShopIO&quot;)
                ],
              ),
            )),
        bottom: PreferredSize(
            child: Container(
              color: lightGray,
              height: 1.0,
              width: _width - 30,
            ),
            preferredSize: const Size.fromHeight(0)),
      );
  
  </code></pre>
