1、接入高德地图
要去看官方库!!!!!
flutter,引入simple_permissions依赖后,ios编译报错simple_permissions-Swift.h' file not found
报错:
=== BUILD TARGET url_launcher OF PROJECT Pods WITH CONFIGURATION Debug ===
/Users/liyan/software/flutter/.pub-cache/hosted/pub.flutter-io.cn/simple_permissions-0.1.9/ios/Classes/SimplePermissionsPlugin.m:2:9: fatal error: 'simple_permissions/simple_permissions-Swift.h' file not found
#import <simple_permissions/simple_permissions-Swift.h>
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1 error generated.
解决方法:
进入flutter_project/ios/,编辑Podfile,将
platform :ios, '9.0'
替换为:
platform :ios, '10.0'
use_frameworks!
关键是use_frameworks!
2、使用dart2.7新特性(扩展语法)

3、flutter build ios --release 报错
Preparing
Analyzing dependencies
Inspecting targets to integrate
Using `ARCHS` setting to build architectures of target `Pods-Runner`: (``)
.....
改Podfile文件
platform :ios, '10.0' 库支持的低版本,看具体什么库
报443的
在文件里面加上
source 'https://github.com/CocoaPods/Specs.git'
use_frameworks!
4、Scaffold里面弹出软键盘导致界面异常
加载这个属性 resizeToAvoidBottomPadding: false,
5、指定数值变化(例如在2秒内从0升到255)
@override
void initState() {
super.initState();
AnimationController animatedContainer = AnimationController(duration: Duration(milliseconds: 150),vsync: this);
Animation<int> alpha = IntTween(begin: 180, end: 370).animate(animatedContainer);
alpha.addListener(() {
setState(() {
meunHeight = alpha.value;
});
});
}
void startAnim(){
if(isShow){
animatedContainer.forward();
isShow = false;
}else{
animatedContainer.reverse();
isShow = true;
}
}
2、flutter接入支付宝登录
导入 fake_alipay: ^0.2.3
这个有bug需要改源码:
1、Alipay->211行的(RsaSigner)类
2、在这个文件里面找到(RsaKeyParser)类
3、修改RsaKeyParser类的parsePrivate方法
修改前
class RsaKeyParser{
...
RSAPrivateKey parsePrivate(String key) {
List<String> rows = key.split('\n');
String header = rows.first;
if (header == '-----BEGIN RSA PRIVATE KEY-----') {
return _parsePrivate(_parseSequence(rows));
}
if (header == '-----BEGIN PRIVATE KEY-----') {
return _parsePrivate(_pkcs8PrivateSequence(_parseSequence(rows)));
}
throw UnsupportedError('PEMKey($key) is unsupported');
}
}
修后
class RsaKeyParser{
...
RSAPrivateKey parsePrivate(String key) {
List<String> rows = key.split('\n');
String header = rows.first;
// if (header == '-----BEGIN RSA PRIVATE KEY-----') {
// return _parsePrivate(_parseSequence(rows));
// }
// if (header == '-----BEGIN PRIVATE KEY-----') {
return _parsePrivate(_pkcs8PrivateSequence(_parseSequence(rows)));
// }
throw UnsupportedError('PEMKey($key) is unsupported');
}
}
6、[!] Error installing libwebp [!] /usr/local/bin/git clone
https://www.jianshu.com/p/2ad9ea97303a
https://github.com/webmproject/libwebp.git
7、xcode 打包后闪退
other links 添加 -all_load
8、Flutter优化,外接纹理(使用原生View,主工程是flutter)
9、Flutter优化,无侵入的外接纹理(主工程是android或者是IOS,已插件的形式导入原生工程)
10、清除缓存
flutter clean
rm -Rf ios/Pods
rm -Rf ios/.symlinks
rm -Rf ios/Flutter/Flutter.framework
rm -Rf ios/Flutter/Flutter.podspec
11、flutter 打包安卓瘦包(知道arm-v7a内核)
flutter build apk --release --target-platform android-arm
12、问题:ios包提示重复,xcode选择传统模式就运行,androidstudio 每次编译自动选择严格模式
