Here are only the most important parts of the code to illustrate how to use the library. 34 | 35 | Generate bytes to print through [flutter_esc_pos_utils](https://pub.dev/packages/flutter_esc_pos_utils). 36 | 37 | ```dart 38 | import 'package:esc_pos_utils/esc_pos_utils.dart'; 39 | 40 | final profile = await CapabilityProfile.load(); 41 | final generator = Generator(PaperSize.mm58, profile); 42 | List bytes = []; 43 | 44 | bytes += generator.text('Test Print', styles: const PosStyles(align: PosAlign.center)); 45 | bytes += generator.text('Product 1'); 46 | bytes += generator.text('Product 2'); 47 | ``` 48 | 49 | ## Android 50 | Allow to connect bluetooth (classic and BLE), USB and network devices 51 | 52 | ### Change the minSdkVersion for Android 53 | 54 | thermal_printer is compatible only from version 21 of Android SDK so you should change this in android/app/build.gradle: 55 | 56 | In build.gradle set 57 | ``` 58 | defaultConfig { 59 | ... 60 | minSdkVersion 19 61 | targetSdkVersion 33 62 | ... 63 | ``` 64 | 65 | select type of device `PrinterType` ( bluetooth, usb, network) 66 | 67 | if select bluetooth you can send optional params 68 | 69 | - isBle -> allow to connect with bluetooth that supports this technology 70 | - autoconnect -> allow to reconnect when state of device is None 71 | 72 | USB: you can enable the native broadcast receiver to notify connected usb devices 73 | put the following code in AndroidManifest 74 | ``` 75 | 78 | 79 | 80 | 81 | 82 | 83 | 84 | 85 | ``` 86 | 87 | ## iOS 88 | Allow to connect bluetooth (BLE) and network devices 89 | 90 | ## Windows 91 | Allow to connect USB and network devices 92 | To network devices is necessary to set ipAddress 93 | 94 | 95 | ## How to use it 96 | ### init a PrinterManager instance 97 | 98 | ```dart 99 | import 'package:thermal_printer/thermal_printer.dart';

resources to get you started if this is your first Flutter project: 10 | 11 | - [Lab: Write your first Flutter app](https://flutter.dev/docs/get-started/codelab) 12 | - [Cookbook: Useful Flutter samples](https://flutter.dev/docs/cookbook) 13 | 14 | For help getting started with Flutter, view our 15 | [online documentation](https://flutter.dev/docs), which offers tutorials, 16 | samples, guidance on mobile development, and a full API reference. 17 | -------------------------------------------------------------------------------- /example/analysis_options.yaml: -------------------------------------------------------------------------------- 1 | # This file configures the analyzer, which statically analyzes Dart code to 2 | # check for errors, warnings, and lints. 3 | # 4 | # The issues identified by the analyzer are surfaced in the UI of Dart-enabled 5 | # IDEs (https://dart.dev/tools#ides-and-editors). The analyzer can also be 6 | # invoked from the command line by running `flutter analyze`. 7 | 8 | # The following line activates a set of recommended lints for Flutter apps, 9 | # packages, and plugins designed to encourage good coding practices. 10 | include: package:flutter_lints/flutter.yaml 11 | 12 | linter: 13 | # The lint rules applied to this project can be customized in the 14 | # section below to disable rules from the `package:flutter_lints/flutter.yaml` 15 | # included above or to enable additional rules.
