Flutter Tutorial - Search Bar Field In AppBar [2022]

how to create a search bar in flutter let's start with a search icon within the app bar if we press on the search icon then we call a message show search whereas we can implement inside of a new class our search behavior and we need to override here four methods with this we can already click on the search icon and then we have the search bar within our app next you can define the leading icon within the search bar and also the clear action icon within the search bar if we click on the leading icon then we want to close the search with this if i click on this arrow back button then we go back to our previous screen and secondly if we click on the clear action button then we want to remove the input of our search bar with this if we click on this clear button then the input of the search bar is cleared in case the search bar is already empty then we also want to close our search as a result since the search input is empty and we click on the clear button we close the search next under the search bar we want to build the suggestions therefore we create a list of suggestions that we display inside of a list view builder and each suggestions we want to build as a list tile with this we have a list of suggestions displayed under the search bar if we click on one suggestion then we want to put the suggestion into our search input with this if i click on the suggestion then you see the search input is changing after this we call also the message show results and with this we don't display anymore the suggestions instead we display the results and in our case we simply display then the query our search input with this if we click on a suggestion then we display the result page and lastly if we type anything into the search bar then we want to update our suggestions therefore we create within our class a search results list and inside the suggestions we map over our search results and for each of the search results we check then basically if our result contains the such input with this we only display the suggestions that match with the search input let's also try it out i type here something different and you see always the suggestions are updated [Music]
