Your "problem" is that you are using a beta version of Dart 2.12 which enables the non-nullable feature. This feature will help you ensure you are aware of all situations where a null value can happen. In your case it is the call to stdin.readLineSync():

Returns null if no bytes preceded the end of input.

You are getting an error because double.parse takes a String as argument but stdin.readLineSync() are returning String? which are a type which can be a String or null (where String only allows String and can never be null).

The easy fix is to do the following and inserting ! after readLineSync():

The issue is with your deletion function. You are updating the function to show only the deleted row. You need something like: Pass the index from your html

The issue here is that you are mixing detail row by row information in the same query as group or aggregated data. Aggregated data will output a single value for all the rows unless you have a group by clause. If you have a group by clause then it will output a single value for each group. When you are grouping you can also include any values that are in the group by clause since they will be unique for the group.

if you want this data for each employee, then you could group by employee_id. Any other data would need to also be an aggregate like Max(Adjusted_Hire_Date)

As you can see, the canActivate can return Observable or Promise which allows for asynchronous operations. So you need to write it in an async manner to handle the case when user role is not yet fetched. Something like:

Use secrets. Documentation can be found at:

Also check out 'Configuration and Secrets' chapter of 'Deploying to OpenShift' book at:

The book is a free download.

You also don't have to have your code up up GitHub. You can use a binary input build. This is also covered in that book.

You didn't execute the flow.

After the flow is created, call either complete() (blocking) or start() to execute it. Calling stop() is not going to execute the flow.
