I'm making a bool condition for search and review cart page then i face these 3 errors i try to solve but not success(first 2 error on container //Expected to find ','. //The element type 'bool' can't be assigned to the list type 'Widget'. )and the second one on the text widget(Expected to find ']'.)

bool isBool = false;
  SigleItem(this.isBool);



 isBool ==false  Container( //Expected to find ','. //The element type 'bool' can't be assigned to the list type 'Widget'.
                  margin: const EdgeInsets.only(right: 15),
                  padding: const EdgeInsets.symmetric(horizontal: 10),
                  height: 35,
                  decoration: BoxDecoration(
                    border: Border.all(color: Colors.grey),
                    borderRadius: BorderRadius.circular(30),
                  ),
                  child: Row(
                    children: [
                      const Expanded(
                        child: Text(
                          'RS-799',
                          style: TextStyle(
                            color: Colors.grey,
                          ),
                        ),
                      ),
                      Center(
                        child: Icon(

You forgot the use question mark. You need to use like this.

isBool == false ? Container(
                  margin: const EdgeInsets.only(right: 15),
                  padding: const EdgeInsets.symmetric(horizontal: 10),
                  height: 35,
                  decoration: BoxDecoration(
                    border: Border.all(color: Colors.grey),
                    borderRadius: BorderRadius.circular(30),
                  ),
                  child: Row(
                    children: [
                      const Expanded(
                        child: Text(
                          'RS-799',
                          style: TextStyle(
                            color: Colors.grey,
                          ),
                        ),
                      ),
                      Center(
                        child: Icon(
                          Icons.arrow_drop_down,

                        ),
                      ),
                    ],
                  ),
                ):Text('750'),

You can directly use ternary operator like this

isBool ? text("if true then show this") : text("if false then show this)

boool_var ? true_widget : false_widget
