How to make this design using widgets in flutter

If you want just your container take it:

Container(
          color: Color(0xffffe3b5),
          padding: const EdgeInsets.all(10),
          child: Row(
            mainAxisAlignment: MainAxisAlignment.center,
            mainAxisSize: MainAxisSize.max,
            crossAxisAlignment: CrossAxisAlignment.center,
            children: [
              Expanded(
                child: Column(
                  children: [
                    Text("60+", style: TextStyle(fontWeight: FontWeight.bold, fontSize: 20),), 
                    SizedBox(height: 5,),
                    Text("Cryptos", style: TextStyle(fontSize: 15),)
                  ],
                ),
              ),
              Expanded(
                child: Column(
                  children: [
                    Text("5k+", style: TextStyle(fontWeight: FontWeight.bold, fontSize: 20),), 
                    SizedBox(height: 5,),
                    Text("Active users", style: TextStyle(fontSize: 15),)
                  ],
                ),
              ),
              Expanded(
                child: Column(
                  children: [
                    Text("100%", style: TextStyle(fontWeight: FontWeight.bold, fontSize: 20),), 
                    SizedBox(height: 5,),
                    Text("Positive Results", style: TextStyle(fontSize: 15),)
                  ],
                ),
              )
            ],
          ),
        ),

If you want to overlay widgets use the Stack widget
