在 TextFormField 中,prefixIcon 采用一个小部件,
我使用了 Image.asset(lock,width: 10,height: 10,),
但它的尺寸比 20 大,
我所做的?
最佳答案
您可以在 TextFormField 小部件中添加 prefixIcon,如下所示,
prefixIcon: Padding(
padding: const EdgeInsets.all(10.0),
child: Image.asset(
'assets/facebook_logo.jpg',
width: 20,
height: 20,
fit: BoxFit.fill,
),
),
prefixIcon is a 48*48 px wide widget by default as per flutter documentation. so to decrease the size of the icon add the padding on all the size and you will be able to adjust as per your requirements.
