Create Sign-in-with-Google button in Flutter in accordance with the terms

I'd like to add a "Sign in with Google" Button to my Flutter app. This button should be in accordance with the terms of Google.

My problem is, that the button I've create looks really awful.

I used the images which Google provides on their website but I don't know if I'm doing right with the code for the button.

  Widget _createLoginButtonGoogle() {
    return new Expanded(
      child: new Container(
        margin: EdgeInsets.fromLTRB(30.0, 5.0, 30.0, 5.0),
        child: new RaisedButton(
          color: const Color(0xFF4285F4),
          shape: _createButtonBorder(),
          onPressed: () {},
          child: new Row(
            children: <Widget>[
              new Image.asset(
                'res/images/icons/google/btn_google_dark_normal_mdpi.9.png',
                height: 48.0,
              ),
              new Expanded(
                child: _createButtonText('Sign in with Google', Colors.white),
              ),
            ],
          ),
        ),
      ),
    );
  }

What I want is that my button looks like the original Google button

original google button

And not like my version

my version of the google button

Can anyone tell me how to create the original google button? Is there a better way than creating a RaisedButton?

I'm giving you a general idea, replace Android icon with your Google image using Image.asset(google_image)

InkWell(
  onTap: () {},
  child: Ink(
    color: Color(0xFF397AF3),
    child: Padding(
      padding: EdgeInsets.all(6),
      child: Wrap(
        crossAxisAlignment: WrapCrossAlignment.center,
        children: [
          Icon(Icons.android), // <-- Use 'Image.asset(...)' here
          SizedBox(width: 12),
          Text('Sign in with Google'),
        ],
      ),
    ),
  ),
)

you can use Padding property of raised button also use property of Row widget and mainAxisSize of button. Following code may help you to understand clearly.

 new Container(
      margin: EdgeInsets.fromLTRB(30.0, 5.0, 30.0, 5.0),
      child: new RaisedButton(
        padding: EdgeInsets.only(top: 3.0,bottom: 3.0,left: 3.0),
        color: const Color(0xFF4285F4),
        onPressed: () {},
        child: new Row(
          mainAxisSize: MainAxisSize.min,
          children: <Widget>[
            new Image.asset(
              'res/images/icons/google/btn_google_dark_normal_mdpi.9.png',
              height: 48.0,
            ),
            new Container(
              padding: EdgeInsets.only(left: 10.0,right: 10.0),
                child: new Text("Sign in with Google",style: TextStyle(color: Colors.white,fontWeight: FontWeight.bold),)
            ),

                          style: TextStyle(
                            fontSize: 20,
                            color: Colors.black54,
                            fontWeight: FontWeight.w600,
                          ),
                        ),
                      ),
                    ],
                  ),
                ),
              ),

for more you can change the Text font to Roboto Medium and make the size 14x, based on the branding rule https://developers.google.com/identity/branding-guidelines#font
