their is no need to create asset directory and under it images directory and then you put image. Better is to just create Images directory inside your project where pubspec.yaml exist and put images inside it and access that images just like as shown in tutorial/documention

assets: - images/lake.jpg // inside pubspec.yaml

The problem is in your pubspec yaml  here you need to delete the last comma    uses-material-design  true

I think the error is caused by the redundant      flutter    uses-material-design  true     lt  lt  lt  redundant   at the end of the line   assets      - images lake jpg   I d also suggest to create an assets folder in the directory that contains the pubspec yaml file and move images there and use  flutter    uses-material-design  true   assets      - assets images lake jpg   The assets directory will get some additional IDE support that you won t have if you put assets somewhere else

An alternative way to put images in your app  for me it just worked that way    1 - Create an assets images folder  2 - Add your image to the new folder  3 - Register the assets folder in pubspec yaml  4 - Use this code   import  package flutter material dart    void main     gt  runApp MyApp      class MyApp extends StatelessWidget      override   Widget build BuildContext context         var assetsImage   new AssetImage  assets images mountain jpg       lt - Creates an object that fetches an image      var image   new Image image  assetsImage  fit  BoxFit cover      lt - Creates a widget that displays an image       return MaterialApp        home  Scaffold          appBar  AppBar            title  Text  Climb your mountain               backgroundColor  Colors amber 600      lt - background color to combine with the picture  -                     body  Container child  image      lt - place where the image appears

Create images folder in root level of your project       Drop your image in this folder  it should look like    Go to your pubspec yaml file  add assets header and pay close attention to all the spaces     flutter     uses-material-design  true      add this   assets      - images profile jpg  Tap on Packages get at the top right corner of the IDE     Now you can use your image anywhere using   Image asset  images profile jpg

When you adding assets directory in pubspec yaml file give more attention in to spaces  this is wrong  flutter     assets      - assets images lake jpg   This is the correct way   flutter    assets      - assets images

Create your assets directory the same as lib level  like this   projectName  -android  -ios  -lib  -assets  -pubspec yaml   then your pubspec yaml like     flutter    assets      - assets images    now you can use Image asset   assets images

How to include images in your app 1  Create an assets images folder  This should be located in the root of your project  in the same folder as your pubspec yaml file  In Android Studio you can right click in the Project view You don t have to call it assets or images  You don t even need to make images a subfolder  Whatever name you use  though  is what you will regester in the pubspec yaml file   2  Add your image to the new folder  You can just copy your image into assets images  The relative path of lake jpg  for example  would be assets images lake jpg   3  Register the assets folder in pubspec yaml  Open the pubspec yaml file that is in the root of your project   Add an assets subsection to the flutter section like this    flutter      assets        - assets images lake jpg   If you have multiple images that you want to include then you can leave off the file name and just use the directory name  include the final       flutter      assets        - assets images     4  Use the image in code  Get the asset in an Image widget with Image asset  assets images lake jpg     The entire main dart file is here    import  package flutter material dart      void main     gt  runApp MyApp        class MyApp extends StatelessWidget        override     Widget build BuildContext context          return MaterialApp          home  Scaffold            appBar  AppBar              title  Text  quot Image from assets quot                           body  Image asset  assets images lake jpg          lt --- image                                  5  Restart your app When making changes to pubspec yaml I find that I often need to completely stop my app and restart it again  especially when adding assets  Otherwise I get a crash  Running the app now you should have something like this   Further reading  See the documentation for how to do things like provide alternate images for different densities   Videos The first video here goes into a lot of detail about how to include images in your app  The second video covers more about how to adjust how they look   Flutter Tutorial - 1 2 Image - Deep Dive Flutter Tutorial - 2 2 Image - Deep Dive
