我用 2 个这样的小部件创建 Row

Row(
   children: [
      new Radio(
        value: 0,
        groupValue: rv0,
        onChanged: _handleRadioValueChange1,
      ),

      GestureDetector(
         onTap: (){ //trigger radio button },
         child: Text('Tap Me')
      )
   ],
)

因此，当我点击文本时，收音机将被触发，例如在带有 jquery 的 javascript 中

$('#radio').click()

在 dart flutter 中如何做到这一点？谢谢

我在 flutter 中创建了新应用程序，运行它时它可以工作，但是当我添加 shared_preferences 包时，运行它时出现此错误

我尝试了这段代码，但结果只是大写第一个字母（不是每个字母）

String ucwords(String input) {
    if (input == null) {
      throw new ArgumentError("string: $input");
    }
    if (input.length == 0) {
      return input;
    }
    return input[0].toUpperCase() + input.substring(1);
}
