How to create inner shadow in textfield Flutter?-CodePudding

I want to create the textfield which should looks like this on the picture. As I unerstood it creates with inner shadow to reach such effect as on the pic. How can I recreate this? I was trying to write code like this, but it also dosen't look like as I would like.

The code I tried:

 Container(
                            width: 450,
                            height: 50,
                            decoration: BoxDecoration(
                                borderRadius:
                                    BorderRadius.all(Radius.circular(5))),
                            padding: EdgeInsets.all(10),
                            child: Container(
                              padding: EdgeInsets.zero,
                              decoration: BoxDecoration(
                                  color: Colors.indigoAccent,
                                  borderRadius:
                                      BorderRadius.all(Radius.circular(8)),
                                  boxShadow: [
                                    BoxShadow(
                                        color: Colors.blue,
                                        blurRadius: 2,
                                        spreadRadius: 2)
                                  ]),
                              width: double.infinity,
                              height: 20,
                              child: Center(
                                child: Text("Content goes here"),
                              ),
                            ))

You can try it:

Container(
      decoration: ShapeDecoration(
        gradient: LinearGradient(
          colors: [Color(0xFFe6dfd8), Color(0xFFf7f5ec)],
          begin: Alignment.topCenter,
          end: Alignment.bottomCenter,
          stops: [0.0, 0.4],
          tileMode: TileMode.clamp,
        ),
        shape: RoundedRectangleBorder(
          borderRadius: BorderRadius.all(Radius.circular(32.0)),
        ),
      ),
      child: TextField(
          expands: false, 
            style: TextStyle(fontSize: 20.0, color: Colors.black54),
            decoration: InputDecoration(
              contentPadding: EdgeInsets.all(12.0),
              prefixIcon: Icon(
                Icons.email,
                color: Colors.black54,
              ),
              hintText: 'email',
              hintStyle: TextStyle(color: Colors.black54),
              focusedBorder: OutlineInputBorder(
                borderSide: BorderSide(color: Colors.white),
                borderRadius: BorderRadius.circular(32.0),
              ),
              enabledBorder: UnderlineInputBorder(
                borderSide: BorderSide(color: Colors.white),
                borderRadius: BorderRadius.circular(32.0),
              ),
            ),
          ),
    );
