Flutter expansionTile 标题填充

Question

我们如何删除 Flutter ExpansionTile 中行首和标题之间的 space？

Answer 1

尝试用 Alignment 包裹你的 title，如下所示

title: Align(
      child: Text(
          "Your text over here"
      ),
      //You may change value from -1.5 to anything which works better for you
      alignment: Alignment(-1.5, 0),
    ),
    dense: true,
  )

Answer 2

请尝试以下片段

ExpansionTile(title: Row(children: [
  // Icon View,
  // SizedBox of desired width,
  // Text View
  ]),
  children:  ... ,)

如果你想删除视图外的填充将 ExpantionTile 图块填充设置为零

ExpansionTile(tilePadding: EdgeInsets.zero, 
     title: Row(children: [
  // Icon View,
  // SizedBox of desired width,
  // Text View
  ]),
  children:  ... ,)
