ffloat's Issues

可否增加内容溢出屏幕自动偏移或限制浮层区域范围

当浮出文字过长时会溢出屏幕看不见，是否可以增加个属性是否限制在屏幕内部？
当锚点在屏幕边缘时基本上浮层都会溢出屏幕，是否可以增加个属性让浮层自动偏移回屏幕内部？

页面前进或者回退存在问题

当我在一个页面打开一个弹层后，我去到新的页面，这个弹层还是会带过去，返回也是有问题

FFloatController的dismiss 不起作用

1.初始化controller,
FFloatController _floatController;
@OverRide
void initState() {
super.initState();
_floatController = FFloatController();
_floatController.setStateChangedListener(() {
});
}

2。在使用的地方引用controller,
controller: _floatController,
alignment: FFloatAlignment.leftCenter,
shadowColor: ColorUtil.cf4f4f4,
// shadowBlur: 14,
shadowOffset: Offset(0.0, 0.0),
corner: FFloatCorner.all(3),
color: Colors.black,
canTouchOutside: true,
triangleAlignment: TriangleAlignment.center,
triangleOffset: Offset(0, 0),
triangleWidth: 10,
triangleHeight: 10,

anchor: Image(
image: AssetImage(
Utils.getImgPath("morepoint"),
),
),

3.在点击事件中隐藏。
InkWell(
onTap: () {
Utils.showToast("msg");
_floatController.dismiss();})

4、结果：
界面上有一个吐司弹出来。但这个ffloat还是没有被隐藏。

获取到MaterialApp中的navigator创建的Overlay。此时的overlay是全局的，如果当前界面收到某些事件回调导致跳转，会导致卡死。
