The element type 'List<Widget>' can't be assigned to the list type 'Widget-CodePudding

 postModel.loading
                ? Center(child: CircularProgressIndicator(),)
                :
            ...renderVideoCards()

This code is part of the column the part that was generating error is ( ...renderVideoCards() ). So let me know where i am going wrong and what should i do to reslove this error

CodePudding user response：

You are trying to assign List type to Widget. You need to change it to a single widget to assign in Widget.

CodePudding user response：

I believe the spread operator ... doesn't work well together with the ternary expression. I believe writing it like this would solve it for you:

if (postModel.loading) Center(child: CircularProgressIndicator()) 
else ...renderVideoCards(),

or alternatively write it like this:

...postModel.loading
  ? [Center(child: CircularProgressIndicator())]
  : renderVideoCards()

CodePudding user response：

I'm guessing that your renderVideoCards() function returns a List<Widget>. So you are trying to assign a List somewhere where you should assing a single Widget.

You can fix this problem by using a Column or a Row: that is a single Widget with multiple children.

postModel.loading
                ? Center(child: CircularProgressIndicator(),)
                :
            ...Column(children: renderVideoCards())
