Separate widgets for Search and Results


Separated widgets for firestore search

Pub Version GitHub Workflow Status Github Stars GitHub

Saves You from following implementations

  • Search AppBar - An AppBar that turns into a TextInputField that takes search queries from users
  • Search Body - A body that shoes up when user starts typing in the Search AppBar
  • Cloud FireStore Queries - Takes user's input and queries the requested CloudFirestore collection

Simple Usage

To use this plugin, add firestore_search as a dependency in your pubspec.yaml file.

Major Update 0.1.7

Separated widgets for search and results.

Use FirestoreSearchBar to display a search field and provide a unique tag that will be passed to the respective FirestoreSearchResults.builder to display results from the requested queries.

FirestoreSearchBar

FirestoreSearchBar(
                tag: 'example',
              )

FirestoreSearchResults.builder

FirestoreSearchResults.builder(
              tag: 'example',
              firestoreCollectionName: 'packages',
              searchBy: 'tool',
              initialBody: const Center(child: Text('Initial body'),),
              dataListFromSnapshot: DataModel().dataListFromSnapshot,
              builder: (context, snapshot) {
                if (snapshot.hasData) {
                  final List<DataModel>? dataList = snapshot.data;
                  if (dataList!.isEmpty) {
                    return const Center(
                      child: Text('No Results Returned'),
                    );
                  }
                  return ListView.builder(
                      itemCount: dataList.length,
                      itemBuilder: (context, index) {
                        final DataModel data = dataList[index];

                        return Column(
                          mainAxisSize: MainAxisSize.min,
                          mainAxisAlignment: MainAxisAlignment.center,
                          crossAxisAlignment: CrossAxisAlignment.start,
                          children: [
                            Padding(
                              padding: const EdgeInsets.all(8.0),
                              child: Text(
                                '${data.name}',
                                style: Theme.of(context).textTheme.headline6,
                              ),
                            ),
                            Padding(
                              padding: const EdgeInsets.only(
                                  bottom: 8.0, left: 8.0, right: 8.0),
                              child: Text('${data.developer}',
                                  style: Theme.of(context).textTheme.bodyText1),
                            )
                          ],
                        );
                      });
                }

                if (snapshot.connectionState == ConnectionState.done) {
                  if (!snapshot.hasData) {
                    return const Center(
                      child: Text('No Results Returned'),
                    );
                  }
                }
                return const Center(
                  child: CircularProgressIndicator(),
                );
              },
            )

Implementation:

  • Import import 'package:firestore_search/firestore_search.dart';

  • Create a data model, for the data you want retrieve from Cloud FireStore (Your data model class must contain a function to convert QuerySnapshot from Cloud Firestore to a list of objects of your data model)

class DataModel {
  final String? name;
  final String? developer;
  final String? framework;
  final String? tool;

  DataModel({this.name, this.developer, this.framework, this.tool});

  //Create a method to convert QuerySnapshot from Cloud Firestore to a list of objects of this DataModel
  //This function in essential to the working of FirestoreSearchScaffold

  List<DataModel> dataListFromSnapshot(QuerySnapshot querySnapshot) {
    return querySnapshot.docs.map((snapshot) {
      final Map<String, dynamic> dataMap =
          snapshot.data() as Map<String, dynamic>;

      return DataModel(
          name: dataMap['name'],
          developer: dataMap['developer'],
          framework: dataMap['framework'],
          tool: dataMap['tool']);
    }).toList();
  }
}
  • Use class FirestoreSearchScaffold and provide the required parameters
FirestoreSearchScaffold(
      firestoreCollectionName: 'packages',
      searchBy: 'tool',
      scaffoldBody: Center(),
      dataListFromSnapshot: DataModel().dataListFromSnapshot,
      builder: (context, snapshot) {
        if (snapshot.hasData) {
          final List<DataModel>? dataList = snapshot.data;
          if (dataList!.isEmpty) {
            return const Center(
              child: Text('No Results Returned'),
            );
          }
          return ListView.builder(
              itemCount: dataList.length,
              itemBuilder: (context, index) {
                final DataModel data = dataList[index];

                return Column(
                  mainAxisSize: MainAxisSize.min,
                  mainAxisAlignment: MainAxisAlignment.center,
                  crossAxisAlignment: CrossAxisAlignment.start,
                  children: [
                    Padding(
                      padding: const EdgeInsets.all(8.0),
                      child: Text(
                        '${data.name}',
                        style: Theme.of(context).textTheme.headline6,
                      ),
                    ),
                    Padding(
                      padding: const EdgeInsets.only(
                          bottom: 8.0, left: 8.0, right: 8.0),
                      child: Text('${data.developer}',
                          style: Theme.of(context).textTheme.bodyText1),
                    )
                  ],
                );
              });
        }

        if (snapshot.connectionState == ConnectionState.done) {
          if (!snapshot.hasData) {
            return const Center(
              child: Text('No Results Returned'),
            );
          }
        }
        return const Center(
          child: CircularProgressIndicator(),
        );
      },
    )

You are good to go 💯

In order to add the FirestoreSearchScaffold in your app, there are several attributes that are important and neglecting them or treating them roughly might throw errors:

Attribute Type Default Required Description
scaffoldBody Widget Widget No This widget will appear in the body of Scaffold.
appBarBottom PreferredSizeWidget null No This widget will appear at the bottom of Search AppBar.
firestoreCollectionName String `` Yes Determines the Cloud Firestore collection You want to search in.
searchBy String `` Yes Key for the firestore_collection value you want to search by.
dataListFromSnapshot List Function(QuerySnapshot) null Yes This function converts QuerySnapshot to A List of required data.
builder Widget Function(BuildContext, AsyncSnapshot) null No This is the builder function of StreamBuilder used by this widget to show search results.
limitOfRetrievedData int 10 No Determines the number of documents returned by the search query.
