You can set control clicked data like toggleShow with boolean type and use v-if for your component trigger

Breaking it down, what you are after is not that complicated.

First off, your maximum/minimum range is from -4 up till 4. Taking into consideration the decimal section, you can have the following: ^[+-]?4(,0{1,2})?$. So in here, we expect a + or a - (optionally), the number 4, optionally followed by a comma and one or two 0's.

In your case, we now need to match the middle of your range, that is, from -3.99 up till 3.99. This can be achieved as follows: ^[+-]?[0-3](,\d{1,2})?$. In this case, we are also expecting a + or a - (optionally). We then expect to match a digit, between 0 and 3, optionally followed by a comma and 1 or 2 digits.

Combining them, we end up with something like so: ^[+-]?((4(,0{1,2})?)|([0-3](,\d{1,2})?))$. Example available here.

EDIT: As per the comments, you need to escape the slash in front of the \d, because the C# compiler will try and find a special meaning for \d, just like it does when you do \n, or \t. The easiest way is to use the @ character, so that the C# compiler threats the string as a literal: Regex regex = new Regex(@"^[+-]?((4(,0{1,2})?)|([0-3](,\d{1,2})?))$");.

Yes..,,you can use inputType as number

Earlier days we know we needed to cast every return type of findViewById() method. Like

usual way

There are two errors in your Gradle build:

Attribute meta-data#onesignal_app_id@value at [com.onesignal:OneSignal:3.6.2] AndroidManifest.xml:52:13-48 requires a placeholder substitution but no value for is provided.

Attribute meta-data#onesignal_google_project_number@value at AndroidManifest.xml requires a placeholder substitution but no value for is provided.

According to the onesignal documentation, you need to provide both of these in order to use the plugin - https://documentation.onesignal.com/docs/android-sdk-setup

So, you could include, in your app/App_Resources/Android/app.gradle the following:
