I'm a big fan of Flutter. But, I don't agree with this comment: "choosing to develop another common application with standard technology, doesn’t make any sense". I agree that there are many advantages to switching to Flutter, but for most companies, it doesn't make any sense to switch over from an existing tech stack to Flutter IMO. A lot of the issues mentioned have nothing to do with languages or frameworks, but simply the person who coded the app in the first place. It's often just a poorly built app.
