I made a android app with flutter webview.
In android gadget, it really works efficiently, however in ios atmosphere it simply exhibits me black display screen.
Are there some fallacious strains?

I anticipate app to point out me regular display screen…
That is first time making app, so I haven’t got sufficient expertise..
