Flutter TextField 设置边框无效

在使用TextField组件时,想要设置外边框颜色,按照下面写法设定无效

TextField(
          decoration: InputDecoration(
              contentPadding: EdgeInsets.all(10.0),
              border: OutlineInputBorder(
                  borderRadius: BorderRadius.circular(0.0),
                  borderSide: BorderSide(color: Colors.red, width: 5, style: BorderStyle.solid))),
          )

查看Flutter源码发现,这个是由于TextFiele Border优先级影响到了

看注释说明,只有到前面几个border为空才会使用border,

正确的设置TexrField边框方式如下

TextField(
          decoration: InputDecoration(
              contentPadding: EdgeInsets.all(10.0),
              enabledBorder:OutlineInputBorder(
                borderRadius: BorderRadius.circular(0.0),
                borderSide: BorderSide(color: Colors.red, width: 0.5, style: BorderStyle.solid)),
              focusedBorder:OutlineInputBorder(
                  borderRadius: BorderRadius.circular(0.0),
                  borderSide: BorderSide(color: Colors.red, width: 0.5, style: BorderStyle.solid)),
              ),
          )

 优先设定enableBorder和focuseBorder
