flutter - 如何将行对齐到固定位置

Question

我有这个List view.builder

child: ListView.builder(
              itemCount: coins.length,
              itemBuilder: (BuildContext context, int index) {
                return ListTile(
                  leading: iconsList[index],
                  title: Wrap(children: [
                    Row(children: [
                      Text(
                        coins[index],
                        style: const TextStyle(color: Colors.white),
                      ),
                      Text(
                        value[index],
                        style: TextStyle(color: Colors.white),
                      ),
                    ]),
                  ]),
                  subtitle: Align(
                    alignment: Alignment.bottomRight,
                    child: Text(
                      value[index],
                      style: TextStyle(color: Colors.white),
                    ),
                  ),
                );
              }),

只需在Row下使用mainAxisAlignment: MainAxisAlignment.spaceBetween和crossAxisAlignment: CrossAxisAlignment.center,，无需使用字幕，只需绑定(bind)右侧即可带有 Column 的侧边元素并根据需要更改文本样式

ListTile(
               leading: Icon(Icons.add),
              title: Wrap(children: [
                Row(
                    mainAxisAlignment: MainAxisAlignment.spaceBetween,
                    crossAxisAlignment: CrossAxisAlignment.center,
                    children: [
                      Text(
                        "coins[index]1",
                        style: const TextStyle(color: Colors.white),
                      ),
                      Column(
                        children: [
                          Text(
                            "value[index]2",
                            style: TextStyle(color: Colors.white),
                          ),
                          Text(
                            "value[index]3",
                            style: TextStyle(color: Colors.white),
                          ),
                        ],
                      )

                    ]),
              ]),

            )

输出:
