Flutter：如何在文本与蓝色Container间添加内边距？

要在蓝色Container和下方文本之间添加间距，只需在Column的两个子Widget之间插入垂直间距组件即可，常用两种实现方式：

方式一：用SizedBox设置固定高度间距 #

在蓝色Container与下方Center组件之间添加SizedBox(height: 30)（高度值可按需调整）：

body: Column(
  mainAxisSize: MainAxisSize.min,
  crossAxisAlignment: CrossAxisAlignment.start,
  children: <Widget>[
    Container(
      padding: EdgeInsets.only(left: 25, bottom: 24),
      width: double.infinity,
      decoration: BoxDecoration(
        color: Color.fromARGB(255, 92, 172, 178),
        borderRadius: BorderRadius.only(
          bottomLeft: Radius.circular(36),
          bottomRight: Radius.circular(36),
        )
      ),
      child: const Text(
        "Olá, usuário",
        style: TextStyle(
          color: Colors.white,
          fontWeight: FontWeight.bold,
          fontSize: 35,
        ),
      )
    ),
    // 添加垂直间距
    SizedBox(height: 30),
    Center(child: Text(
      "As suas finanças estão:",
      style: TextStyle(
        color: Colors.black,
        fontSize: 18,
      )),
    )
  ],
),

方式二：用Padding给文本添加上内边距 #

给包裹文本的Center组件套一层Padding，设置top方向的内边距：

body: Column(
  mainAxisSize: MainAxisSize.min,
  crossAxisAlignment: CrossAxisAlignment.start,
  children: <Widget>[
    Container(
      padding: EdgeInsets.only(left: 25, bottom: 24),
      width: double.infinity,
      decoration: BoxDecoration(
        color: Color.fromARGB(255, 92, 172, 178),
        borderRadius: BorderRadius.only(
          bottomLeft: Radius.circular(36),
          bottomRight: Radius.circular(36),
        )
      ),
      child: const Text(
        "Olá, usuário",
        style: TextStyle(
          color: Colors.white,
          fontWeight: FontWeight.bold,
          fontSize: 35,
        ),
      )
    ),
    Padding(
      padding: EdgeInsets.only(top: 30),
      child: Center(child: Text(
        "As suas finanças estão:",
        style: TextStyle(
          color: Colors.black,
          fontSize: 18,
        )),
      ),
    )
  ],
),

两种方式都能实现你要的效果，调整数值可控制间距大小，按需选择即可。
