flutter pub add ensure_visible_when_focused基于插件公开信息、社区数据与项目使用情况整理的选型参考。
一个 Flutter 小部件，当特定小部件获得焦点时，会自动滚动视口以确保其可见。对于内容较长的表单，此包通过防止输入字段被键盘遮挡来提升可用性。它可在所有主要平台上运行，包括移动设备、网页和桌面端，提供无缝的用户体验。该小部件可轻松集成到现有的表单布局中，无需复杂的滚动逻辑。

I was having a hard time scrolling to a specific wdget in a scenario where I had a very large form, with lots of form fields.
I found an issue with no concrete answer https://github.com/flutter/flutter/issues/58877
After digging a litlle deeper I found a solution to this problem https://www.didierboelens.com/2018/04/hint-4 -ensure-a-textfield-or-textformfield-is-visible-in-the-viewport-when-has-the-focus/. Hence the idea of creating and making this widget available.
This widget solves this problem in a very elegant way. You just have to give the same FocusNode of the widget you want to scroll to.
The widget is very simple to use. You need to Wrap your widget on a EnsureVisibleWhenFocused widget. You have to pass the FocusNode of the widget you want to scroll to when it's given focus.
EnsureVisibleWhenFocused(
focusNode: _focusNode,
child: TextFormField(
focusNode: _focusNode,
),
)
With the setup above, every time the TextFormField gains focus, a scroll will be made to it.
You can give focus to a field just doing:
_focusNode.requestFocus();
You can configure more things, such as the scroll duration and it's curve.
