how to initialize a map in flutter/dart with widgets-CodePudding

what i am trying to is have containers widget to have unique id so that i can uniquely identify them i have tried :

  Map<int,Container> box={
    1:Container(),
    2:Container(),
    3:Container(),
  };

  Map<int,Widget> box={
    1:Container(),
    2:Container(),
    3:Container(),
  };

Column(
        mainAxisAlignment: MainAxisAlignment.start,
        children:<Widget> [
          box[1],
        ],
      ),

Column(
        mainAxisAlignment: MainAxisAlignment.start,
        children:[
          box[1],
        ],
      ),

tried both

is there any way to do this .

CodePudding user response：

I believe you are trying to use List<Widget>

Define:

List<Widget> list = [Container(), Container(), Container()];

Use:

Column(
  children: [list[0]],
);
