Apache configure server root – Change Localhost to Domain
Linux Add custom bash commands
Step 1 :
Find your .bashrc file
Step 2 :
(.bashrc is found in root directory)
(You can type cd in the terminal and hit enter to get to root and use ls -la to see list of files in directory)
- Edit your .bashrc file. Use whatever editing tool of your choice.
or you can just edit in the terminal with the below command :
nano .bashrc
Once you are in the file proceed to step 3.
Step 3 :
Go to the bottom of you .bashrc file and look for something along the lines of the below :
export NVM_DIR="$HOME/.nvm" [ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm [ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion" # This loads nvm bash_completion
Step 4 :
Add a comment above the snippet indicated above so it looks like this.
#Custom Bash Commands # Commands will be listed here... export NVM_DIR="$HOME/.nvm" [ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm [ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion" # This loads nvm bash_completion
Step 5 :
Add your commands. 1 per line! use semi-colon ( ; ) to run multiple commands in succession
#Custom Bash Commands alias my_custom_bash_command="do something in bash code" alias my_custom_bash_command2="do something in bash code" alias my_custom_bash_command3="do something in bash code" alias my_custom_bash_command4="do something in bash code" export NVM_DIR="$HOME/.nvm" [ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm [ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion" # This loads nvm bash_completion

DropdownButtonFormField & Validation from API
Requirements :
- API Service
- Object Model
Developer Recommendation : NB!!! - Use QuickType for your model.
(You need an already working api with a JSON response for quicktype) https://app.quicktype.io/
- DropDownMenuItem
NB!!! - The DropDownMenuItem must be wrapped in a form widget to implement validation.
HINT : Avoid casting variable types such as <String> or <List> or <Object> until your list is actually working. In the DropdownButtonFormField Snippet, you will see no types are declared.
Step 1 :
Configuration :
(On your page.dart or screen.dart)
You need to include these.
1 : Your Model from QuickType
// Model import './model/support_fields_model.dart'; // API import 'package:project_name/api/support_fields_service.dart'; // Includes import 'package:flutter/material.dart';
DropdownButtonFormField Snippet :
child: Form(
key: globalFormKey,
Container(
child: DropdownButtonFormField(
hint: Text("-- Select Query --"),
value: querySelect,
validator: (querySelect) =>
querySelect ==
"-- Select Query --"
? 'Select Query Required'
: null,
onChanged: (newValue) {
setState(() {
dropDownButtonCallback(
newValue, "select_query");
});
},
items: querySelectOptions
.map<DropdownMenuItem>((map) {
return DropdownMenuItem(
value: map.name,
child: Text(map.name),
);
}).toList(),
), // DropdownButtonFormField
), // Container
), // Form
Excell Calculations for Text after and Before Space
Excel give characters after space
If you want to extract the text after space only, use this formula
=MID(A1,FIND(" ",A1)+1,256)
Excel give characters before space
Extract text before or after space with formula in ExcelYou can quickly extract the text before space from the list only by using formula. Select a blank cell, and type this formula
=LEFT(A1,(FIND(" ",A1,1)-1))
(A1 is the first cell of the list you want to extract text) , and press Enter button.
