final password = TextFormField(
autofocus: false,
obscureText: true,
decoration: InputDecoration(
hintText: 'Password',
contentPadding: EdgeInsets.fromLTRB(20.0, 10.0, 20.0, 10.0),
prefixIcon: new ImageIcon(
new AssetImage('assets/ic_email.png'),
size: 15.0,
),
),
);
我将尺寸设置为15.0,但没有任何变化,所以请指导我,我在哪里做错了?

只需在 Image.asset 中设置属性即可获得解决方案,请尝试以下方法
final password = TextFormField(
autofocus: false,
obscureText: true,
decoration: InputDecoration(
hintText: 'Password',
contentPadding: EdgeInsets.fromLTRB(20.0, 10.0, 20.0, 10.0),
prefixIcon: new IconButton(
icon: new Image.asset('assets/ic_email.png',width: 15.0,height: 15.0,),
onPressed: null,
),
),
);
