══╡ EXCEPTION CAUGHT BY WIDGETS LIBRARY ╞═══════════════════════════════════════════════════════════
The following assertion was thrown building _InkResponseStateWidget(gestures: [tap], mouseCursor:
null, clipped to BoxShape.rectangle, dirty, state: _InkResponseState#f9ca6):
No Material widget found.
_InkResponseStateWidget widgets require a Material widget ancestor.
In material design, most widgets are conceptually "printed" on a sheet of material. In Flutter's
material library, that material is represented by the Material widget. It is the Material widget
that renders ink splashes, for instance. Because of this, many material library widgets require that
there be a Material widget in the tree above them.
To introduce a Material widget, you can either directly include one, or use a widget that contains
Material itself, such as a Card, Dialog, Drawer, or Scaffold.
The specific widget that could not find a Material ancestor was:
  _InkResponseStateWidget
The ancestors of this widget were:
  ...
  InkWell
  Column
  _SingleChildViewport
  IgnorePointer-[GlobalKey#aad43]
  Semantics
  ...

Which widget is causing the error?

The widget which are without Material ancestors are listed on the error message, here in our case, the widget without ancestors are:

The ancestors of this widget were:
  ...
  InkWell
  Column
  _SingleChildViewport
  IgnorePointer-[GlobalKey#aad43]
  Semantics
  ...
