asset image not appearing in flutter-CodePudding

I am using dhiwise to convert my figma prototype into flutter but the header is not appearing and is somehow above the screen. I tried moving it elsewhere but it just puts it outside the header.

current look what it is supposed to look like

return SafeArea(
 child: Scaffold(
 backgroundColor: ColorConstant.whiteA700,
 body: Container(
 height: size.height,
 width: size.width,
 child: Stack(
 children: [
 Align(
 alignment: Alignment.center,
 child: SingleChildScrollView(
 child: Container(
 height: size.height,
 width: size.width,
 child: Stack(
 alignment: Alignment.topRight,
 children: [
 Align(
 alignment: Alignment.center,
 child: Container(
 height: size.height,
 width: size.width,
 decoration: BoxDecoration(

 ),
 child: Stack(

 children: [
 Align(
 alignment: Alignment.topCenter,
 child: Container(
 width: size.width,
 padding: getPadding(
 left: 11,
 top: 7,
 right: 11,
 bottom: 7,
 ),
 decoration: BoxDecoration(

 ),
 child: Column(
 mainAxisSize: MainAxisSize.min,

 MainAxisAlignment.start,
 children: [
 CustomIconButton(
 height: 53,
 width: 53,
 margin: getMargin(
 bottom: 276,
 ),
 child: CustomImageView(
 svgPath: ImageConstant.imgUser,

the custom image view code, this code was directly from the website itself and I have no idea what any of the code means to do

CodePudding user response：

1- flutter clean

2- flutter pub get

And if it doesn't work with these instructions, I suggest you look at the link below enter link description here

CodePudding user response：

I hope you specified that image as an asset in the pubspec.yaml.

I mean...

Flutter uses the pubspec.yaml file, located at the root of your project, to identify assets required by an app.

flutter:
  assets:
    - assets/my_icon.png
    - assets/background.png

To include all assets under a directory, specify the directory name with the / character at the end:

flutter:
  assets:
    - directory/
    - directory/subdirectory/

CodePudding user response：

If you already specify path of your image (sometimes you need to hot restart if you add new asset)

please check that svg image was fine by opening it via web. I face the same issues before with svg using SvgPicture I can open svg file on web but not readble in mobile apps. As I remember my error was not valid svg.

This library only supports <defs> and xlink:href references that are defined ahead of their references.

If do so, maybe you can try this one.

save image as PNG from Figma
Import image to Adobe XD
Export to SVG.
Replace current asset with this Adobe XD svg format.
