编写 TextStyle
lib/pages/splash.dart
// 标题
const Text(
"Online Market",
style: TextStyle(
fontSize: 19,
fontFamily: "Poppins",
fontWeight: FontWeight.bold,
color: Colors.white,
height: 22 / 19,
),
),
fontFamily
中写入字体名称Poppins
height
文本跨度的行高将为 [fontSize] 的倍数并且正好是fontSize *height
逻辑像素 高。换行的时候才有意义。
加入间距
标题和图标间距 24,和计数器 27
lib/pages/splash.dart
// 主视图
Widget _buildView(BuildContext context) {
return Column(
mainAxisAlignment: MainAxisAlignment.center,
crossAxisAlignment: CrossAxisAlignment.center,
children: [
// 图标
_buildLogo(),
const SizedBox(height: 24),
// 标题
const Text(
"Online Market",
style: TextStyle(
fontSize: 19,
fontFamily: "Poppins",
fontWeight: FontWeight.bold,
color: Colors.white,
height: 22 / 19,
),
),
const SizedBox(height: 27),
// 倒计时
const Text(
"10",
style: TextStyle(
fontSize: 19,
fontFamily: "Poppins",
fontWeight: FontWeight.bold,
color: Colors.white,
height: 22 / 19,
),
),
],
);
}
