Set Error Message on Spinner and EditText in Android when user cannot select any option

Notify user when Spinner and EditText is Empty
I want to notify the user if the spinner field is not selected. How can I perform such a  notification without using a Toast?
Try these line of code in your project which are give below:
Write these of code on onCreate ( ) Method
Here return statement will stop the flow of your program
Spinner
Spinner remarks = (Spinner) findViewById(R.id.sp_remarks2);


if (remarksvalue.equalsIgnoreCase("Select")) {
    TextView errorText = (TextView)remarks.getSelectedView();    errorText.setError(" Please Select Remarks");    errorText.setTextColor(Color.RED);//just to highlight that this is an error    errorText.setText("Please Select Remarks");    return;}
EditText
EditText et_newreading = (EditText)findViewById(R.id.ed_light);


if (newreadingvl.isEmpty()) {
    et_newreading.setError("Please Enter Meter Reading");    return;}

Expected a key while parsing a block mapping (Flutter)

Flutter makes use of the Dart packaging system, pub. Via your applications  pubspec.yam l file (or simple pubspec), you can pull down packages from the flutter ecosystem, or the broader dart community. Anyway, i need to add some images to my flutter application, and so had to add an assets section to the pubspec .the default Android Studio generated apps pubspec has a lot of commented out code with explainations about what is going on, e.g # To add assets to your application, add an assets section, like this: # assets: # - images/a_dot_burr.jpeg # - images/a_dot_ham.jpeg # An image asset can refer to one or more resolution-specific "variants", see # https://flutter.io/assets-and-images/#resolution-aware. So I uncommented these lines # assest : - - - #  -  images/a_dot_ham.jpeg with the idea from these comment.  that i would just edit it to suit my particular needs. Once you have edited your  pubspec, you need to click on the "Get dependencies"
