In Flutter, to create a color from RGB with alpha, use:

return new Container(
 color: new Color.fromRGBO(0, 0, 0, 0.5),
);

How to use hexadecimal color:

return new Container(
 color: new Color(0xFF4286f4),
);
// 0xFF -> the opacity (FF for opaque)
// 4286f4 -> the hexadecimal color

Hexadecimal color with opacity:

return new Container(
 color: new Color(0xFF4286f4).withOpacity(0.5),
);

// Or change the "FF" value
