關於flutter使用高德地圖search api

pub搜了下amap_base_flutter屬於評分比較高的了

參考https://github.com/flutter/flutter/pull/34369

編譯的時候報錯

e: C:\flutter\.pub-cache\hosted\pub.flutter-io.cn\amap_base_search-0.4.1\android\src\main\kotlin\me\yohom\amapbasesearch\search\SearchHandlers.kt: (326, 1): Object 'DistanceSearchHandler' is not abstract and does not implement abstract member @UiThread public abstract fun onMethodCall(@NonNull p0: MethodCall, @NonNull p1: MethodChannel.Result): Unit defined in me.yohom.amapbasesearch.SearchMethodHandler
e: C:\flutter\.pub-cache\hosted\pub.flutter-io.cn\amap_base_search-0.4.1\android\src\main\kotlin\me\yohom\amapbasesearch\search\SearchHandlers.kt: (327, 5): 'onMethodCall' overrides nothing

插件的源碼有問題需要改下，這個因為作者比較忙一直沒修，問了下說這周會出版本

amap_base_flutter-master\search\android\src\main\kotlin\me\yohom\amapbasesearch\search\SearchHandlers.kt line 327

object DistanceSearchHandler : SearchMethodHandler {
    override fun onMethodCall(call: MethodCall, result: MethodChannel.Result?) {//去掉問號

改完后編譯通過安裝后閃退，查了下應該是32位64位的問題，--target-platform參數已經棄用了 unused flag `--target-platform` from `flutter run`直接改配置文件C:\flutter\packages\flutter_tools\lib\src\android\gradle.dart line 461

 command.add('-Ptarget-platform=android-arm');

原有項目增加amap_base_search時編譯報錯，單個dex file文件過大，解決方案參考https://www.jianshu.com/p/f68b0b070c31

D8: Cannot fit requested classes in a single dex file (# methods: 67205 > 65536)

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:transformDexArchiveWithExternalLibsDexMergerForDebug'.
> com.android.builder.dexing.DexArchiveMergerException: Error while merging dex archives: 
  The number of method references in a .dex file cannot exceed 64K.

 源碼還有個問題C:/flutter/.pub-cache/hosted/pub.flutter-io.cn/amap_base_search-0.4.1/lib/src/search/amap_search.dart 文件里的L.p方法不存在，都替換為print方式
