【Flutter】改变TextField 边框颜色

本篇为本人平时总结的经验,如有更好的写法请留言。

TextField(
      autofocus: true,
      controller: TextEditingController.fromValue(TextEditingValue(
          text: value,
          selection: TextSelection.fromPosition(TextPosition(
              affinity: TextAffinity.downstream, offset: value.length)))),
      decoration: InputDecoration(
        contentPadding: EdgeInsets.fromLTRB(isHaveUnit ? 20 : 8, 0, 8, 0),
        enabledBorder: OutlineInputBorder(
            borderSide: BorderSide(color: Color(0xffB6B6B6), width: 0.5)),
        focusedBorder: OutlineInputBorder(
            borderSide: BorderSide(color: Color(0xffFD3F2A), width: 1)),
      ),
      textAlign: TextAlign.right,
      inputFormatters: [
        WhitelistingTextInputFormatter(RegExp("[0-9.-]")),
      ],
      keyboardType: TextInputType.number,
      onChanged: onChanged,
    );

直接设置border的颜色不起作用,包括这只theme的border的颜色也是,需要设置enabledBorder,focusedBorder的border颜色并且制定border宽度才会修改成功。
