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

Question

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

And not like my version

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

Solution 1

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),)
            ),
          ],
        )
      ),
    ),

Wouldn't conform to the guidelines like this: developers.google.com/identity/branding-guidelines?hl=en

@kuemme01 That's why I mentioned to use your own asset there.
