1、构造函数

public RaisedButton(
                Key key = null,
                VoidCallback onPressed = null,//点击回调为null时按钮禁用
                ValueChanged<bool> onHighlightChanged = null,//按下回调ture ；抬起为false
                ButtonTextTheme? textTheme = null,//主题
                Color textColor = null,//文字颜色
                Color disabledTextColor = null,//按钮禁用时候文字的颜色
                Color color = null,//按钮的背景颜色
                Color disabledColor = null,//按钮被禁用的时候显示的颜色
                Color highlightColor = null,//按钮高亮颜色
                Color splashColor = null,//按钮闪烁颜色
                Brightness? colorBrightness = null,//按钮主题 Brightness.dark黑色Brightness.light，亮光
                float? elevation = null,//按钮下面的阴影
                float? highlightElevation = null,//高亮时候的阴影
                float? disabledElevation = null,//抬起时候的阴影
                EdgeInsets padding = null,
                ShapeBorder shape = null,//按钮材质的形状
                Clip? clipBehavior = Clip.none,//Clip.none完全没有剪辑。Clip.hardEdge剪辑，但不应用抗锯齿。Clip.antiAlias剪辑具有抗锯齿功能。Clip.antiAliasWithSaveLayer,//在剪辑后立即剪辑具有抗锯齿和saveLayer
                MaterialTapTargetSize? materialTapTargetSize = null,//MaterialTapTargetSize.padded将最小点击目标大小扩展到48px乘以48px。MaterialTapTargetSize. shrinkWrap将目标尺寸缩小到最小值
                TimeSpan? animationDuration = null,//动画时间
                Widget child = null
            )

2、例子

new  Container(
                padding: EdgeInsets.all(10.0f),
                child:new Column(
                  children:new List <Widget>(){
                      new RaisedButton(
                      onPressed: ()=>{},
                      child:new Text("文本的颜色红色，背景颜色黑色，按钮按下的颜色蓝色"),
                      textColor:Colors.red,
                      color: Colors.black,
                      highlightColor:Colors.blue
                    ),
                  new   RaisedButton(
                      onPressed: null,
                      child:new  Text("disabledTextColor禁用时文本颜色，disabledColor禁用时背景颜色"),
                      disabledTextColor:new  Color(0xff999999),
                      disabledColor: new Color(0xffff0000)
                    ),
                   new  RaisedButton(
                      onPressed: ()=>{},
                      child:new  Text("splashColor闪烁颜色，disabledColor禁用时背景颜色"),
                      splashColor:new  Color(0xffff0000)
                    ),
                   new  RaisedButton(
                      onPressed: ()=>{},
                      child:new  Text("colorBrightness按钮主题高亮 Brightness.light"),
                      colorBrightness: Brightness.light
                    ),
                  new   RaisedButton(
                      onPressed: ()=>{},
                      child: new Text("colorBrightness按钮主题高亮 Brightness.dark"),
                      colorBrightness: Brightness.dark
                    ),
                  new   Container(
                      margin: EdgeInsets.only(top: 20.0f),
                      child: new RaisedButton(
                        onPressed: ()=>{},
                        child:new  Text(
                            "elevation按钮下面的阴影,highlightElevation高亮时候的阴影,disabledElevation按下的时候的阴影"),
                        elevation: 5.0f
                      )
                    ),
                   new  Container(
                      margin: EdgeInsets.only(top: 20.0f),
                      child:new  RaisedButton(
                        onPressed: ()=> {},
                        child: new Text(
                            "elevation按钮下面的阴影,highlightElevation高亮时候的阴影,disabledElevation按下的时候的阴影"),
                        highlightElevation: 5
                      )
                    ),
                   new  Container(
                      margin: EdgeInsets.only(top: 20.0f),
