Difference between const and final in Dart
• Even though both const
and final
cannot be reassigned, there is a subtle difference between them.
• const
variables are used for compile-time constants whereas final
variables are used for run-time constants.
const current_time = new DateTime.now() // DON'T do it as the value is computed at run time
const name = 'Rahul' // DO it as the value is known at compile time
• When reading from database or reading from a file, the values won't be known at compile time. Use final
in such cases

figured out how we can use gitignore
to add the .DS_STORE files into it by deleting the ds.store file first , and then using echo ".DS_Store" >> .gitignore
to add the .ds_store file.

I've have a radio
input in a React Hook form
and attempted to pass a boolean
value, however when i submit the form, i receive the typeof
value as a string
. Knowing that RHF
has valueAsNumber
to convert it as number
. I thought that setValueAs
was a generic way to allow any conversion but I can't make it work.
I learn how to extract a boolean
value from a RHF
radio input
.
The setValueAs
approach, which I have previously tried, only functions with text input (such as type="text" or type="number"). Even if the value for a radio button is a string, it doesn't function.
In order to fix it, a Controller component can be used.
Solution:-
<Controller
defaultValue={false}
control={control}
name="booking_for_someone"
render={({ field: { onChange, onBlur, value, ref } }) => (
<label className="booking-for-someone">
<span className="f-semibold">{t("I'm Booking For")}</span>
<div>
<input
type="radio"
onBlur={onBlur}
onChange={() => onChange(false)}
checked={value === false}
inputRef={ref}
id="myself"
/>
<label
htmlFor="myself"
>
{t("Myself")}
</label>
</div>
<div >
<input
type="radio"
className="w-16 h-16 rounded-full accent-blue"
onBlur={onBlur}
onChange={() => onChange(true)}
checked={value === true}
inputRef={ref}
id="someone-else"
/>
<label
htmlFor="someone-else"
>
{t("Someone Else")}
</label>
</div>
</label>
)}
/>
Thanks :slightly_smiling_face:

Unsubscribe Feature when Email Service Provider is AWS SES
AWS SES List Management
• AWS SES provides built-in feature for managing email subscribers and their subscription preferences. This includes creating contact lists and topics, and enabling unsubscribe functionality directly in our emails.
• We need to create separate topics for different types of emails: To handle different types of emails like verification links
, subscription updates
, marketing
etc. we can create separate topics for each type of email. This allows us to manage the subscription preferences for each type of email separately.
• We need to Include the {{amazonSESUnsubscribeUrl}}
placeholder in our emails: AWS SES will automatically replace the {{amazonSESUnsubscribeUrl}}
placeholder in the email with the actual unsubscribe URL.
• When a user clicks on this link, they will be taken to an unsubscribe landing page hosted by AWS, where they can choose to opt-out of receiving emails for a specific topic or all topics.
• AWS SES will handle the process of updating the user's subscription status when they opt-out of a topic. The next time when our system tries to send an email to that user for the opted-out topic, AWS SES will not allow the email to be sent.
• Ensure important emails are not affected: To ensure that users can still receive important emails like OTP verification
and password reset
emails, even after they opt-out of other emails, we can use separate contact lists and topics for these types of emails or we should not pass ListManagementOptions
in these emails.

in ruby if we have a variable called a = “HELLO” and then we assign it to a new variable
b = a
it does not create a deep copy of the string "Hello"
stored in a
. Instead, it creates a new variable b
that references the same string object in memory as a
. Both a
and b
will point to the same memory location, which means they will hold the same value and any changes made through one variable will be reflected in the other.
so if we do
b.upcase!
it will return
puts a # Output: "HELLO"
puts b # Output: "HELLO"
If we want to create a separate copy of the string, we can use the dup
method or string manipulation methods to create a new string object with the same content.
