I want to create customised widget using ArcGIS API for flex (in adobe flash builder). I surfed internet and all the samples I found of widgets use ArcGIS viewer for flex. Has anybody has the experience on creating widget using adobe flash builder? where should I start?

I am using Adobe Flex SDK 4.6 and ArcGIS API for Flex 3.6, thanks.

  • I added a flash-builder tag to your question which should link you through to some Q&As here as a place to start.

1 Answer 1


To start with your custom widget, you need

  • ArcGIS for Flexviewer3.6 source code
  • ArcGIS API 3.6 for Flex.

You can download

  • Flexviewer3.6 source code from GitHub.
  • AcrGIS API 3.6 for Flex from esri under ArcGIS API for Flex section.

Steps to import the source code to Flash Builder:

  1. Flash Builder -> File -> Import Flash Builder Project.
  2. Browse to downloaded source code zip file and Open the file.
  3. Give name to project. (optional)
  4. Click Finish.

Steps to add ArcGIS API to your flexveiwer:

  1. Extract the arcgis_api_for_flex_3_6.zip file.
  2. Copy the file ArcGIS_Flex\libs\agslib-3.6-2013-12-13.swc from extracted folder.
  3. Go to Flash Builder and expand the imported flexveiwer project.
  4. Paste the file in libs folder under flexveiwer project.

Now you are good to go.

you can add ArcGIS API to your flexveiwer from Flex Build Path too but above mentioned steps are simpler.
