Modo de usar

• Usando componente BaseWidget em um StatelessWidget

import 'package:flutter/material.dart';
import 'package:easy_comp/easy_comp.dart';

class EasyCompTeste extends BaseWidget {
  EasyCompTeste({Key? key});

  @override
  Widget builder(BuildContext context, BoxConstraints constrains) {
    return Container(
      child: Center(
        child: Text("Usando BaseWidget"),
      ),
    );
  }
}

• Usando componente BasefulWidget em um StatefulWidget

import 'package:flutter/material.dart';
import 'package:easy_comp/easy_comp.dart';

class EasyCompTeste extends BasefulWidget {
  EasyCompTeste({Key? key});
  @override
  _EasyCompTesteState createState() => _EasyCompTesteState();
}

class _EasyCompTesteState extends BasefulWidgetState<EasyCompTeste> {
  @override
  Widget builder(BuildContext context, BoxConstraints constrains) {
    return Container(
      child: Center(
        child: Text("Usando BaseWidgetFull"),
      ),
    );
  }
}

• Usando componente BaseState em um StatefulWidget

import 'package:easy_comp/easy_comp.dart';
import 'package:easy_comp/src/testes/provider_basestate.dart';
import 'package:flutter/material.dart';

class TesteBaseState extends StatefulWidget {
  const TesteBaseState({super.key});
  @override
  BaseState<TesteBaseState, ProviderBaseState> createState() => _TesteBaseStateState();
}

class _TesteBaseStateState extends BaseState<TesteBaseState, ProviderBaseState> {

  @override
  void onInit() {
    super.onInit();
    debugPrint(provider.titulo);

    provider.titulo = "Mudando";
  }

  @override
  void onResume() {
    super.onResume();
    provider.getDadosApi();
  }

  @override
  Widget build(BuildContext context) {
    return Text(provider.titulo);
  }
}

• Usando componente FirebaseFirestoreRepository

import 'dart:developer';

import 'package:cloud_firestore/cloud_firestore.dart';
import 'package:easy_comp/easy_comp.dart';
import 'package:easy_comp/src/utils/utils.dart';


class TesteModel {
  String id = "";
  String nome = "";
  String categoria = "INITIAL";
  TesteModel({
    required this.id,
    required this.nome,
    this.categoria = "INITIAL",
  });

  TesteModel.fromDocument(DocumentSnapshot<Map<String, dynamic>> doc) {
    final map = doc.data()!;
    id = getMap<String>(key: "id", map: map, retur: doc.id);
    nome = getMap<String>(key: "nome", map: map, retur: "");
    categoria = getMap<String>(key: "categoria", map: map, retur: "INITIAL");
  }

  TesteModel.fromJson(Map<String, dynamic> map, String? id) {
    this.id = id ?? (getMap<String>(key: "id", map: map, retur: ""));
    nome = getMap<String>(key: "nome", map: map, retur: "");
    categoria = getMap<String>(key: "categoria", map: map, retur: "INITIAL");
  }

  static Map<String, dynamic> toJson(TesteModel model) => {
        "id": model.id,
        "nome": model.nome,
        "categoria": model.categoria,
      };

  @override
  String toString() => 'Teste(id: $id, nome: $nome, categoria: $categoria)\n';
}

class TesteRepository extends FirebaseFirestoreRepository<TesteModel> {
  TesteRepository()
      : super(
          collectionPath: 'BAIRROS',
          firestore: FirebaseFirestore.instance,
          fromJson: TesteModel.fromJson,
          toJson: TesteModel.toJson,
        );

  @override
  CollectionReference<TesteModel> get collection => super.collection;

  Future<List<TesteModel>> todosByCategoria() async {
    final lista = await collection.where("categoria", isEqualTo: "INITIAL").get().then((value) => value.docs.map((e) => e.data()).toList());
    return lista;
  }
}

void main() async {
  final repo = TesteRepository();
  final todos = await repo.buscarTodos(
    descending: false,
    limit: 10,
    orderBy: "nome",
    where: QueryConstraint(field: "categoria", op: QueryOperation.isEqualTo, value: "INITIAL"),
    // Ou
    whereList: [
      QueryConstraint(field: "categoria", op: QueryOperation.isEqualTo, value: "INITIAL"),
      QueryConstraint(field: "nome", op: QueryOperation.isGreaterThanOrEqualTo, value: "Teste"),
    ],
  );
  log(todos.toString());
}

• Usando componente CustomFuture

import 'package:flutter/material.dart';
import 'package:easy_comp/easy_comp.dart';

class EasyCompTeste extends BaseWidget {
  EasyCompTeste({Key? key});

  Future<List<String>> getValues() async {
    await Future.delayed(const Duration(seconds: 2));
    return ["1", "2", "3"];
  }

  @override
  Widget builder(BuildContext context, BoxConstraints constrains) {
    return Scaffold(
      appBar: AppBar(
        title: const Text("Teste"),
      ),
      body: CustomFuture<List<String>>(
        future: getValues(),
        emptyWidget: const Text("Empty"),
        withLoading: true,
        withError: true,
        erroBuilder: (error) {
          return Text(error.toString());
        },
        builder: (values) {
          return ListView.builder(
            itemCount: values.length,
            itemBuilder: (context, index) {
              return ListTile(
                title: Text(values[index]),
              );
            },
          );
        },
      ),
    );
  }
}
