如何向页面视图 Flutter 添加不同的项目

Question

I have this code which allows me to scroll between cards that hold text. However, all it does is add the same text on each card. I want to display two separate pieces of text which are kept inside

HomeInfo()
Achieve()

This is the code I currently have:

SizedBox(
                    height: 300,
                      child: PageView.builder(
                        itemCount: 2,
                        controller: PageController(viewportFraction: 0.7),
                        onPageChanged: (int index) =>
                            setState(() => _index = index),
                        itemBuilder: (_, i) {
                          return Transform.scale(
                            scale: i == _index ? 1 : 0.9,
                            child: Card(
                              elevation: 6,
                              shape: RoundedRectangleBorder(
                                  borderRadius: BorderRadius.circular(20)),
                              child: Center(
                                child: HomeInfo(),
                              ),
                            ),
                          );
                        },
                      ),
                    ), 

I am really confused on how to do this. (I just started getting into coding) Thanks

You need to check for the index and return the appropriate widget.

You can achieve this way:

SizedBox(
                    height: 300,
                      child: PageView.builder(
                        itemCount: 2,
                        controller: PageController(viewportFraction: 0.7),
                        onPageChanged: (int index) =>
                            setState(() => _index = index),
                        itemBuilder: (_, i) {

                          return Transform.scale(
                            scale: i == _index ? 1 : 0.9,
                            child: Card(
                              elevation: 6,
                              shape: RoundedRectangleBorder(
                                  borderRadius: BorderRadius.circular(20)),
                              child: Center(
                                child: i == 0 ? HomeInfo() : Achieve(), // this line
                              ),
                            ),
                          );
                        },
                      ),
                    ),
