dart - Dart 中角组件的 Material list 的误差

Question

每当我尝试用material-list中的display: inline-flex;填充项目列表时，flex都不会响应，该列表只会水平对齐，但是如果我将HTML代码从material-list更改为ul，则会按预期填充列表。那么，谁能告诉我我做错了什么？


list.html

    <div class="demo-list-content">
     <material-list>
        <material-list-item>
            <material-icon icon="home"></material-icon>
            <div class="demo-list-item">Item 1</div>
        </material-list-item>
        <material-list-item>
            <material-icon icon="home"></material-icon>
            <div class="demo-list-item">Item 1</div>
        </material-list-item>
        <material-list-item>
            <material-icon icon="home"></material-icon>
            <div class="demo-list-item">Item 1</div>
        </material-list-item>
        <material-list-item>
            <material-icon icon="home"></material-icon>
            <div class="demo-list-item">Item 1</div>
        </material-list-item>
        <material-list-item>
            <material-icon icon="home"></material-icon>
            <div class="demo-list-item">Item 1</div>
        </material-list-item>
    </material-list>
</div>

list.css

.demo-list-content {
    margin: 24px;
}

material-list {
    padding: 16px;
    display: inline-flex;
}

material-list-item {
    width: 200px;
    display: inline;
    flex-direction: column;
    border: solid;
    margin: 16px;
    text-align: center;
}

.demo-list-item {

}

如果删除与flex相关的内容并添加以下样式，则应将其包装

.material-list-item {
    float: left;
}
