WebViewState finishLoad calling multiple time

Based on finish load I want to save this url in database. But finishLoad calling multiple time. Why it's behavior is like this?

my code:

_webviewPlugin.onStateChanged.listen((WebViewStateChanged state) async {
if (mounted) {

if(WebViewState.startLoad == state.type){

setState(() {
isProgress = true;
});

}else if(WebViewState.finishLoad == state.type){
isProgress = false;
await database.saveUser(new History(widget.uri.toString(), "Hello title"));

}
}
});

从报告中所示的 _webviewPlugin.onStateChanged listener 和 WebViewState.finishLoad 事件路径开始。使用提供的数据库保存操作重现重复的 finishLoad 通知，然后记录事件生命周期以及应保存 URL 的条件。

由索引模型根据 Issue 内容生成。
