advanced search

AdvancedSearch #
Flutter library provides advanced capabilitis for searching through a predefined list using TextField

How it works? Code talks better: #
List<String> searchableList = ['Orange', 'Watermelon', 'Banana', ...etc];

AdvancedSearch( // This is basically an Input Text Field
data: searchableList,
maxElementsToDisplay: 7,
onItemTap: (index) {
// user just found what he needs, now it's your turn to handle that
},
onSearchClear: () {
// may be display the full list? or Nothing? it's your call
},
onSubmitted: (value, value2) {
// now you have a submitted search
},
onEditingProgress: (value, value2) {
// user is trying to lookup something, may be you want to help him?
},
)

disabledBorderColor // Border color of TextField when it's disabled
focusedBorderColor // Border color of TextField when it's on focus
cursorColor // Cursor Color, nothing more to tell
searchItemsWidget // Here you can pass a function that takes a String (will be replaced by search result item) and returns a Widget which will be used to list the search results instead of the default one [Don't forget to pass a reasonable singleItemHeight if you are passing this attribute]
maxElementsToDisplay (Default = 7) // as search results, what is the Maximum number you want to have
borderRadius (Default = 10.0) // radius for search results list border
fontSize (Default = 14.0) // for TextField and Search Results
singleItemHeight (Default = 45.0) // height for every single item in the search results list
verticalPadding (Default = 10.0) // Vertical Padding for the TextField
horizontalPadding (Default = 10.0) // Horizontal Padding for the TextField
itemsShownAtStart (Default = 10) // if the user didn't start sraching yet but clicked the search TextField, how many items should be displayed to him
hintText (Default = 'Enter a name') // hint text for search TextField
hintTextColor (Default = Colors.grey) // hint text color
autoCorrect (Default = false) // AutoCorrect functioanlity for TextField inputs
enabled (Default = true) // is the search should be enabled now, or not
bgColor (Default = Colors.white) // Background Color for Search Results widget
inputTextFieldBgColor // Background Color for the TextField itself
borderColor (Default = const Color(0xFFFAFAFA)) // Border Color for Search Results widget
searchMode (Default = SearchMode.CONTAINS) // what is the search criteria you want to Apply? should the results CONTAINS, STARTING_WITH, or EXACT_MATCH your search
caseSensitive (Default = false) // want your search to be applied on the searchable list as case sensitive, or not
minLettersForSearch (Default = 0) // what is the minimum letters that the user should type before starting to receive search results
clearSearchEnabled (Default = true) // should the user be able to clear his search, or not
showListOfResults (Default = true) // should a list of results be displayed to the user, or shall you just get what he searches for and you will do your things by your own
hideHintOnTextInputFocus (Default = false) // an option to hide the hin t text once the TextField get focused
autoListing (Default = false) // an option to display the results instandly without searching (in this case it shall display the max elements to be shown)

So basically you can build your widget like that #
AdvancedSearch(
data: ['Orange', 'Watermelon', 'Banana', 'Red Grapes'],
maxElementsToDisplay: 10,
singleItemHeight: 50,
borderColor: Colors.grey,
minLettersForSearch: 0,
selectedTextColor: Color(0xFF3363D9),
fontSize: 14,
borderRadius: 12.0,
hintText: 'Search Me',
cursorColor: Colors.blueGrey,
autoCorrect: false,
focusedBorderColor: Colors.blue,
searchResultsBgColor: Color(0xFAFAFA),
disabledBorderColor: Colors.cyan,
enabledBorderColor: Colors.black,
enabled: true,
caseSensitive: false,
inputTextFieldBgColor: Colors.white10,
clearSearchEnabled: true,
itemsShownAtStart: 10,
searchMode: SearchMode.CONTAINS,
showListOfResults: true,
unSelectedTextColor: Colors.black54,
verticalPadding: 10,
horizontalPadding: 10,
hideHintOnTextInputFocus: true,
hintTextColor: Colors.grey,
onItemTap: (index, value) {
print("selected item index is $index");
},
onSearchClear: () {
print("Cleared Search");
},
onSubmitted: (searchText, listOfResults) {
print("Submitted: " + searchText);
},
onEditingProgress: (searchText, listOfResults) {
print("TextEdited: " + searchText);
print("LENGTH: " + listOfResults.length.toString());
},
),

To give the credit to whom deserve it, I got inspired to do this package by the auto_search package. #
