EasyFlutterPlugin;
in vscode, search "easy-flutter-plugin".
English | 中文
Plug-ins automatically map to generate plug-in method claims based on the lib directory of the flutter plugin project, and developers only need to pay attention to the internal implementation of method;
*.dart => Swift*Plugin.swift/(*Plugin.h + *Plugin.m) + *Plugin.kt/ *Plugin.java + *_test.dart + main.dart
Features
Easy to use, saving time and effort to implement core code.
Usage：
choose /lib/*.dart, and Right-click menu 'Easy Flutter Plugin'
example：
hello_test_two.dart
import 'dart:async';
import 'package:flutter/services.dart';
class HelloTestTwo {
static const MethodChannel _channel = const MethodChannel('hello_test_two');
/// 无参数
static Future<String> getPlatformVersion() async {
String value = await _channel.invokeMethod('getPlatformVersion');
return value;
}
/// 字典参数: Map<String, dynamic>
static Future<String> getAppVersion(Map<String, dynamic> val) async {
String value = await _channel.invokeMethod('getAppVersion', val);
return value;
}
/// 数组参数: List<String>
static Future<String> getAppVersion1(List<String> val) async {
String value = await _channel.invokeMethod('getAppVersion1', val);
return value;
}
/// 字符串参数: String
static Future<String> getAppVersion2(String val) async {
String value = await _channel.invokeMethod('getAppVersion2', val);
return value;
}
/// 整数参数: int
static Future<String> getAppVersion3(int val) async {
String value = await _channel.invokeMethod('getAppVersion3', val);
return value;
}
/// 浮点数参数: double
static Future<String> getAppVersion4(double val) async {
String value = await _channel.invokeMethod('getAppVersion4', val);
return value;
}
/// 布尔值参数: bool
static Future<String> getAppVersion5(bool val) async {
String value = await _channel.invokeMethod('getAppVersion5', val);
return value;
}
}
