我想TextFormField在 Flutter 中加载一个 SVG 图像。我使用了这个SVG 加载库。但是每次 svg 图像显示在中心并且 TextFormField 的提示文本没有显示。我想在TextFormField. 这是我的代码：
Form(
key: _formKey,
child: Column(
children: [
new RectWithBorder(AppColors.white, AppColors.gray, 1.0, BorderRadius.circular(6.0), new EdgeInsets.all(0.0), new Padding(
padding: new EdgeInsets.all(10.0),
child: TextFormField(
decoration: InputDecoration(
border: InputBorder.none,
hintText: Strings.emailOrMobileText,
),
keyboardType: TextInputType.text,
controller: emailController,
validator: Utils.isValidEmailOrMobile,
onSaved: (String value){
this.email = value;
},
))),
new RectWithBorder(AppColors.white, AppColors.gray, 1.0, BorderRadius.circular(6.0), new EdgeInsets.fromLTRB(0, 10.0, 0, 0), new Padding(
padding: new EdgeInsets.all(10.0),
child: TextFormField(
decoration: InputDecoration(
border: InputBorder.none,
hintText: Strings.passwordText,
suffixIcon: new Padding(
padding: const EdgeInsets.all(5.0),
child: new SizedBox(
height: 20,
child: SvgPicture.asset("assets/images/invisible.svg"),
),
),
),
keyboardType: TextInputType.text,
obscureText: true,
validator: _validatePassword,
onSaved: (String value){
this.password = value;
},
),)
),
new RoundedButton(
title: Strings.loginButtonText.toUpperCase(),
backgroundColor: AppColors.accent,
radius: 6.0,
textStyle: new TextStyle(fontSize: 18.0, fontWeight: FontWeight.bold, color: AppColors.white),
textColor: AppColors.white, margin: new EdgeInsets.fromLTRB(0, 20, 0, 0), onPressed: (){
Utils.isConnectedToInternet().then((isConnected){
if(isConnected == null || !isConnected){
Utils.showSnackBar(context, Strings.noInternetConnection);
} else{
// _verifyCaptcha();
_executeLogin(email, password);
}
});
},),
new Container(
margin: new EdgeInsets.fromLTRB(0, 30.0, 0, 0),
child: new GestureDetector(
child: Text(
Strings.forgotPasswordText,
style: new TextStyle(
color: AppColors.primary,
fontSize: 15.0
),
),
))
],
),
),
但它显示 SVG 如下图
任何帮助这是什么问题？
